Obama speaks of hopes for Africa

US President Barack Obama, on his first trip to sub-Saharan Africa since taking office, has said Africa must take charge of its own destiny in the world.

Mr Obama told parliament in Ghana during his one-day stay that good governance was vital for development.

Major challenges awaited Africans in the new century, he said, but vowed that the US would help the continent.

The US president’s trip comes at the end of a summit of eight of the world’s most powerful nations, held in Italy.

Ghana was chosen as the destination for the president’s visit because of its strong democratic record.

Mr Obama headed from parliament to Cape Coast Castle, a seaside fortress converted to the slave trade by the British in the 17th Century. He was accompanied by his wife, Michelle, a descendant of African slaves, and both of his young daughters.

People crowded into a public area outside the fort to greet Mr Obama, with those unable to get a place in the throng climbing onto nearby roofs and filling balconies just to catch a glimpse of the US leader.

Africa’s choice

Mr Obama spoke to parliament shortly after a breakfast meeting with Ghanaian President John Atta Mills.

He wore a broad grin as he was greeted at the podium by a series of rousing horn blasts from within the chamber.

Development depends upon good governance. And that is a responsibility that can only be met by Africans US President Barack Obama

“Congress needs one of them,” Mr Obama joked, before turning to more serious matters.

“I have come here to Ghana for a simple reason,” the US president said: “The 21st Century will be shaped by what happens not just in Rome or Moscow or Washington, but by what happens in Ghana as well.”

Delivering a message that “Africa’s future is up to Africans”, Mr Obama conceded that the legacy of colonialism had helped breed conflict on the continent.

“But the West is not responsible for the destruction of the Zimbabwean economy over the last decade, or wars in which children are enlisted as combatants,” he added.

He praised Ghana’s own progress, governance and economic growth, saying Ghana’s achievements were less dramatic than the liberation struggles of the 20th Century but would ultimately be more significant.

“Development depends upon good governance,” Mr Obama told legislators. “That is the ingredient which has been missing in far too many places, for far too long.

“And that is a responsibility that can only be met by Africans.”

‘Yes you can’

Expanding on his message, Mr Obama said four key areas were critical to the future of Africa and of the entire developing world, citing democracy, opportunity, health and the peaceful resolution of conflict.

ANALYSIS Andrew Harding, BBC News, Accra The speech has gone down extremely well. This is a country that has been enormously proud to play host to Mr Obama and referred to him as a brother. People say endlessly that he is part of the family and they are expecting a great deal of him. It was a very broad-ranging speech but Mr Obama has an ability because of his heritage, his Kenyan father, to reach out and speak to Africans in a way that I think most foreign leaders would find very difficult. There are very few barriers for Mr Obama in this conversation that he is trying to initiate with Africans and I think that this speech will have ticked many, many boxes. This is Mr Obama trying to link Africa into the international community.

He hailed Ghana’s democratic society, calling for strong parliaments, honest police, independent judges and a free press across Africa.

However, there were some blunt words directed at other countries, many of which have been undermined by despotic leaders and corrupt politicians.

“Africa doesn’t need strongmen, it needs strong institutions,” Mr Obama told his audience.

“No person wants to live in a society where the rule of law gives way to the rule of brutality and bribery. That is not democracy, that is tyranny.”

He pledged to continue strong US support for public healthcare initiatives in Africa, and called for sensible use of natural resources such as oil in the face of the threat of climate change.

“Africa is not the crude caricature of a continent at war,” Mr Obama added. “But for far too many Africans, conflict is a part of life, as constant as the sun. He described wars as a “millstone around Africa’s neck”.

“You have the power to hold your leaders accountable, and to build institutions that serve the people,” Mr Obama said, describing freedom as Africa’s “inheritance” and urging the continent to beat disease, end conflict and bring long-lasting change.

In an echo of his presidential election campaign, he drew his speech to a close with a version of his trademark slogan: “Yes you can,” he told the gathered legislators.

Tight security

On the streets of Accra, many billboards welcoming Barack Obama have been erected, including one showing an image of the president and wife with the words: “Ghana loves you”.

Barack Obama’s speech was welcomed by Ghanaians of all ages

People have poured into Accra for a glimpse of the president during his 24-hour stay in Ghana.

But security is tight for the president’s visit, and few ordinary Ghanaians will have the chance to glimpse the first African-American President of the United States.

Mr Obama arrived in the capital late on Friday, fresh from the G8 summit in Italy where heads of state agreed on a $20bn (£12.3bn) fund to bolster agriculture – the main source of income for many sub-Saharan Africans.

Obama lifts ban on abortion funds

US President Barack Obama has lifted a ban on federal funding for foreign family planning agencies that promote or give information about abortion.

The US is one of the biggest supporters of family planning programmes globally, but former president George W Bush blocked funds for abortion services.

Powerful anti-abortion groups in the US have criticised the lifting of the ban.

But aid agencies welcomed the move, saying it would promote women’s health, especially in developing countries.

A White House spokesman said Mr Obama signed the executive order without asking for coverage by the media late on Friday afternoon.

The issue of abortion services remains controversial in the US, pitting pro-life conservative groups against more liberal, pro-choice Americans who back a woman’s right to choose whether or not to have an abortion.

This may be why President Obama signed the order with so little fanfare.

Highly contentious

Organisations that had pressed Mr Obama to make the abortion-ban change were jubilant.

They called the funding ban the “gag rule” because it cuts funds to groups that advocate or lobby for the lifting of abortion restrictions.

The Planned Parenthood Federation of America hailed the president for “lifting the stranglehold on women’s health across the globe with the stroke of a pen.”

“No longer will health care providers be forced to choose between receiving family planning funding and restricting the health care services they provide to women,” the organization said in a statement.

But anti-abortion groups were quick to criticise the reversal of the funding ban.

“President Obama not long ago told the American people that he would support policies to reduce abortions, but today he is effectively guaranteeing more abortions by funding groups that promote abortion as a method of population control,” said Douglas Johnson, legislative director of the National Right to Life Committee.

A 1973 decision by the US Supreme Court legalised abortion.

A Gallup poll conducted last year showed that 54% of Americans think abortion should be allowed under certain circumstances, 28% believe it should be legal under any circumstances, while 17% back a total ban.

See-saw issue

The policy has become a see-saw issue between Republican and Democratic administrations.

Former President Bill Clinton, a Democrat, repealed the policy when he took office in 1993 and George W Bush reinstated it in 2001.

The ruling is also known as the Mexico City Policy, because it was first introduced at a UN conference there in 1984 by former Republican President Ronald Reagan.

In a move related to the lifting of the abortion rule, Mr Obama is also expected to restore funding to the UN Population Fund (UNFPA) in the next budget, the AP news agency reported.

The Bush administration contended that the fund’s work in China supported a Chinese family planning policy of coercive abortion and involuntary sterilisation, claims the UNFPA has vehemently denied.

In a separate move earlier on Friday, US regulators cleared the way for the world’s first study on human embryonic stem cell therapy.

While the decision of the US Food and Drug Administration is independent of White House control, Mr Obama is widely expected to adopt a more pragmatic and science-oriented approach to stem cell research.

Biden and Palin debate

Biden and Palin debate

The two US vice-presidential candidates have traded blows on the financial crisis, climate change and foreign policy in their only TV debate.

Democrat Joe Biden sought to link Republican presidential candidate John McCain to the policies of President Bush, saying he was “no maverick”.

Republican Sarah Palin defended herself against claims of inexperience and said the McCain ticket would bring change.

Voter polls suggested Mr Biden had won but Mrs Palin did better than expected.

The debate at Washington University in St Louis, Missouri, was seen as particularly crucial for Mrs Palin, whose poll ratings have fallen.

Mrs Palin played to her strengths and her image as a mother in touch with ordinary Americans.

For the most part she spoke fluently but simply about the economy, climate change and the war in Iraq, our correspondent says, and there were few of the stumbling gaffes that have become the staple of late-night comedy shows.

Two polls conducted after the debate, by US networks CNN and CBS News, judged Mr Biden the winner. However, the CNN poll found a large majority thought Mrs Palin had done better than expected.

‘Hockey moms’

Asked by moderator Gwen Ifill who was at fault for the current problems with the US banking system, Mrs Palin blamed predatory lenders and “greed and corruption” on Wall Street.

It would be a travesty if we were to quit now in Iraq Sarah Palin Republican VP nominee

Senator McCain would “put partisanship aside” to help resolve the crisis, she said, and had raised the alarm over mortgage giants Fannie Mae and Freddie Mac long ago.

She said “Joe six-packs and hockey moms across the country” – referring to middle-class voters – needed to say “never again” to Wall Street chiefs.

Mrs Palin also accused Democratic presidential candidate Barack Obama of seeking to raise taxes but Mr Biden rejected that claim.

He said the economic crisis was evidence that the policies of the past eight years had been “the worst we’ve ever had” and accused Mr McCain of being “out of touch” on the economy.

Senator Obama’s plan to raise taxes on households earning over $250,000 was “fairness”, Mr Biden said, unlike Mr McCain’s proposals for more tax breaks for big companies.

‘Dead wrong’

On foreign policy, Mrs Palin accused Mr Obama of refusing to acknowledge that the “surge” strategy of extra troops in Iraq had worked.

He’s not been a maverick on virtually anything that people talk about around the kitchen table Joe Biden Democratic VP nominee

“It would be a travesty if we were to quit now in Iraq,” she said, describing Mr Obama’s plan to withdraw combat troops a “white flag of surrender”.

Mr Biden countered by saying Mr McCain had been “dead wrong” on Iraq and had yet to present a plan to end the conflict.

He said the US was wasting $10bn a month in Iraq while ignoring the real front line in the fight against terrorism, Afghanistan.

In turn, Mrs Palin said Mr Obama was naive for saying he was willing to talk directly to the leaders of Iran, North Korea and Cuba. “That is beyond bad judgment. That is dangerous,” she said.

The pair also sparred on the issue of climate change.

Mrs Palin, governor of energy-rich Alaska, said human activities were a factor in climate change but that climatic cycles were also an element. She urged US energy independence as part of the answer.

Key words used most frequently by Joe Biden in the debate

Mr Biden pointed to climate change as one of the major points on which the two campaigns differed, saying: “If you don’t understand what the cause is, it’s virtually impossible to come up with a solution.”

He said he and Mr Obama backed “clean-coal” technology and accused Mr McCain of having voted against funding for alternative energy projects and seeing only one solution: “Drill, drill, drill.”

While Mrs Palin described her party’s candidate as “the consummate maverick”, her rival argued that Mr McCain had followed the Bush administration’s policies on important issues such as Iraq.

“He’s not been a maverick on virtually anything that people talk about around the kitchen table,” Mr Biden said.

Overall, commentators highlighted Mrs Palin’s frequent use of a “folksy” style, for example using expressions like “doggone it” and telling her opponent: “Aw, say it ain’t so, Joe.”

They also noted how Mr Biden appeared emotional as he talked about raising his two young sons alone after a car crash killed his first wife.

Poll shift

According to a Pew Research Center poll, two-thirds of voters planned to follow the debate, far more than in 2004.

Sarah Palin was a huge hit at the Republican convention last month

A new poll by the Washington Post suggests that 60% of voters now see Mrs Palin as lacking the experience to be an effective president.

One-third say they are less likely to vote for Senator McCain, as a result.

Independent voters, who are not affiliated to either political party, have the most sceptical views of the 44-year-old Alaska governor.

Another poll, for CBS News, gives Senator Barack Obama 49% to 40% for Mr McCain.

It is the latest in a series of opinion polls that have shown a significant shift in the direction of Mr Obama since the economic crisis began.

Mrs Palin, whose fiery speech at last month’s Republican convention inspired Christian conservatives, produces unusually strong feelings – both positive and negative – among voters.

Key words used most frequently by Sarah Palin in the debate

Although Mrs Palin has succeeded in mobilising conservative Republicans, her key challenge is to appeal to the swing voters who could determine who will win the battleground states, analysts say.

In particular, she needs to win over the “Wal-Mart moms” – white, working-class married women.

A recent poll of customers of discount giant Wal-Mart suggested that Mr McCain was slightly ahead with this group in Ohio and Florida, while Mr Obama was leading in Virginia and Colorado.

Meanwhile, the McCain campaign is scaling back its operations in another swing state, Michigan, effectively conceding the advantage to Mr Obama there.

Quiet Biden back to the fore

Joe Biden’s task is to paint his rival Sarah Palin as untried and untested

Amid the hyper inflated excitement that still follows Republican vice-presidential candidate Sarah Palin wherever she goes, it is sometimes easy to forget that she has a rival for the job – Joseph Biden.

Remember him? You know, the grey-haired guy Barack Obama picked to be his running mate on the Democratic party ticket.

When he strode out onto the stage in Denver to accept his party’s nomination, Joe Biden had the media’s full attention.

Two days later it was gone. And it seems he has struggled ever since to get it back.

What happened? Sarah Palin happened. Everywhere she goes, a large media posse follows.

In contrast, Joe Biden’s press plane travels the country with a large number of conspicuously empty seats.

Supporters of the Delaware senator say he is quietly getting on with the job, going from town to town, meeting voters, patiently answering their questions and making the case that he and Barack Obama represent the real change in the race for the White House.

Blue collar votes

On the campaign trail Joe Biden has been trying to stress that, with every fibre of his working class roots, he understands the pain of ordinary American families in these troubled economic times – understands in a way, he says, that his old friend John McCain simply cannot.

JOE BIDEN Ran for presidency in 1988 Delaware senator since 1972 A straight talker, who makes occasional gaffes

That, of course, was partly why he was picked: to appeal to an important part of the electorate with which Barack Obama has consistently struggled to connect – blue collar workers.

It was also assumed that Mr Biden would act as the sharp-tongued attack dog, allowing Mr Obama to remain above the fray.

With his long experience in the Senate, especially on the Foreign Affairs Select Committee, it was argued that Joe Biden could simultaneously fill the perceived gaps in Mr Obama’s resume and go toe to toe with John McCain – one old scrapper to another.

Mr Biden has stuck to his task. But he has not set the world on fire. Then again, perhaps he was not meant to – that has always been Barack Obama’s strong suit.

Joe Biden was meant to be the reassuring older hand helping to guide the charismatic presidential challenger safely towards the White House.

He was, in a way, the classic “do no harm” pick for vice-president.

Veep debate

Despite concerns about his reputation for long-winded ramblings, sprinkled with the occasional spice of verbal gaffes, Joe Biden has hardly put a foot wrong.

Two recent quotes have raised some eyebrows though, and, interestingly, perhaps raised his media profile again.

• First, he said Hillary Clinton may have been a better choice for the vice-presidential nomination (after all the effort at the Denver convention to heal party wounds, why on Earth would he want to expose that scar again?)
• Then he said that wealthy people should consider it their patriotic duty to pay higher taxes. That brought rapid fire from the McCain-Palin campaign team and at least got the television pundits talking about him again

But it is his next big moment in the spotlight that will really test Joe Biden’s calibre – the vice-presidential debate in Missouri on 2 October.

Insider v hockey mom?

Joe Biden and Sarah Palin actually have some things in common.

Both claim to speak the language of the ordinary, hard-working, American family. Both eschew ivy league intellectualism. Both have sons serving in Iraq.

Like Joe Biden, Sarah Palin eschews ivy league intellectualism

But, of course, it will be the differences everyone will be focusing on.

Joe Biden’s task will be to paint his opponent as untried and untested; too risky to place a heartbeat away from the presidency.

But he has to make that case without appearing patronising or demeaning, or in any other way opening himself up to the charge of sexism.

The silver-haired, battle-hardened, Washington insider versus the self-styled hockey mom from the remote reaches of Alaska.

It is one of the most keenly anticipated bouts of the entire election, and perhaps more than any of its predecessors, it could have a real influence on the outcome.

Top Republican says Palin unready

Senator Chuck Hagel could be influential with independent voters

Senior Republican Senator Chuck Hagel has voiced doubts about Sarah Palin’s qualifications for the vice-presidency.

John McCain’s running mate “doesn’t have any foreign policy credentials”, Mr Hagel told the Omaha World-Herald.

Mr Hagel was a prominent supporter of Mr McCain during his 2000 bid for the US presidency, but has declined to endorse either candidate this year.

He was opposed to the Iraq War, and recently joined Mr McCain’s rival Barack Obama on a Middle East trip.

‘Stop the nonsense’

“I think it’s a stretch to, in any way, to say that she’s got the experience to be president of the United States,” Mr Hagel told the Omaha World-Herald newspaper.

And he was dismissive of the fact that Mrs Palin, the governor of Alaska, has made few trips abroad.

“You get a passport for the first time in your life last year? I mean, I don’t know what you can say. You can’t say anything.”

This kind of thing will have an effect on independents

Mr Hagel also criticised the McCain campaign for its suggestion that the proximity of Alaska to Russia gave Mrs Palin foreign policy experience.

“I think they ought to be just honest about it and stop the nonsense about, ‘I look out my window and I see Russia and so therefore I know something about Russia’,” he said.

“That kind of thing is insulting to the American people.”

Justin Webb says Mr Hagel’s opinion of Mrs Palin will have an effect on independent voters.

A senior member of the Senate Foreign Relations Committee, Mr Hagel was a close ally of Mr McCain, but the two men parted company over the decision to go to war in Iraq.

Mr Hagel skipped this year’s Republican National Convention in favor of a visit to Latin America.

Mr Hagel’s decision to accompany Mr Obama this summer on a trip to Iraq and Israel, as part of a US Congressional delegation, led to speculation that he would throw his support behind the Democratic nominee.

However, a spokesman for the Nebraska senator insisted in August that “Senator Hagel has no intention of getting involved in any of the campaigns and is not planning to endorse either candidate”.

Record donations month for Obama

Barack Obama’s previous best monthly total was in February

US Democratic presidential candidate Barack Obama raised $66m (£37m) in August, making it his best month in terms of election fund raising.

The amount raised makes it likely Mr Obama will have more to spend than Republican rival John McCain in the final two months before the vote.

Donations were lifted by half a million new donors signing up, an aide said.

The record figure contradicts suggestions that Mr Obama’s fund raising appeal had been slipping.

His previous record, of $55m, was set in February.

The fund raising details are expected to be announced in the coming week when the rival campaigns file their monthly financial reports with the Federal Election Commission.

The public financing of presidential elections as it exists today is broken Barack Obama speaking in June

Mr Obama earlier decided not to accept public financing for the rest of his campaign and now has no spending limit.

He is the first candidate not to take public financing since the system was introduced in the mid-1970s.

Mr McCain did accept public financing, which limits his direct spending to about $84m after 1 September.

Recent opinion polls suggest Mr McCain has a lead of, on average, about 3% over Mr Obama, ahead of the 4 November vote.

Breaking the mould

Correspondents say Mr Obama raised more money than the Republican candidate partly because of the excitement generated by the Democratic nomination battle with Hillary Clinton, which ended on 7 June.

Mr McCain currently leads Mr Obama in opinion polls

Mr McCain, by contrast, wrapped up the Republican nomination back in March.

The only donations he is accepting are those to his compliance fund – money to pay for lawyers, accountants and other expenses involved in maintaining compliance with federal election laws.

The Republican National Committee, however, can still raise money to support the McCain campaign.

The Obama campaign has also broken the mould of US election finance by making big efforts to attract small donors.

Mr Obama explained his decision to shun public finance in June by saying the system was “broken”.

“It’s not an easy decision, and especially because I support a robust system of public financing of elections,” Mr Obama said then in a video message to supporters.

White House race enters high gear

Candidates often see a surge in popularity after the party conventions

The US presidential rivals have begun campaigning in earnest, as a new opinion poll put Republican John McCain ahead of Democrat Barack Obama.

Fresh from being nominated at their party conventions, the two men are now gearing up for the 4 November poll.

A USA Today-Gallup poll put Mr McCain ahead for the first time in months.

Candidates often see a bounce in the polls after the conventions but Mr McCain’s choice of Sarah Palin as running mate is being seen as key.

Mr McCain has tried to strike a balance between distancing himself from an unpopular presidency and rallying the party’s conservative base.

Mrs Palin wowed the Republican convention crowd with her speech, helping to re-energize his campaign.

Major test

Mr McCain said that “the electricity has been incredible” at rallies ever since he invited the Alaskan governor to join his ticket.

“She has excited people all over the country. I would love to say it was all because of the charisma of John McCain, but it is not,” he told CBS on Sunday.

Mr McCain said that “the electricity has been incredible” at rallies

Mrs Palin will face a major test this week when she gives her first nationally televised interview, following intense media scrutiny over her personal life and credentials for the ticket.

The USA Today-Gallup poll, which was released on Sunday, showed Mr McCain leading Mr Obama by four percentage points, 50 to 46.

A USA Today poll taken before the Republican convention showed Mr McCain trailing Mr Obama by seven points.

The latest poll had a margin of error of plus or minus three percentage points.

The results of a Reuters/Zogby poll, also released over the weekend, gave Mr McCain the edge, with 50 percentage points to 46.

The Rasmussen Reports daily Presidential Tracking Poll showed John McCain with a one-point lead.

Mr McCain and Mrs Palin are scheduled to be in Missouri on Monday.

Mr Obama is campaigning in the crucial swing state of Michigan. His vice-president, Joe Biden, was appearing in Wisconsin and Iowa, while Hillary Clinton is on the campaign trail in Florida.

Despite the frenetic pace of the presidential race, the candidates will stop campaigning on Thursday to appear together in New York on the anniversary of the 11 September 2001 attacks.

They said they would put aside politics to honour the memory of the nearly 3,000 people who died.

US rivals to make 9/11 appearance

The candidates have entered the election campaign’s final phase

The US presidential rivals, Barack Obama and John McCain have said they will appear together on the anniversary of the 11 September 2001 attacks.

The senators said they would take part in the commemorations in New York – the site of two of the attacks.

The two candidates said they would put aside politics to honor the memory of the nearly 3,000 people who died.

Hijacked planes were crashed into New York’s Twin Towers, the Pentagon in Washington and a field in Pennsylvania.

“All of us came together on 9/11 – not as Democrats or Republicans – but as Americans,” the joint statement said.

“In smoke-filled corridors and on the steps of the Capitol; at blood banks and at vigils – we were united as one American family.

“On Thursday, we will put aside politics and come together to renew that unity, to honor the memory of each and every American who died, and to grieve with the families and friends who lost loved ones.”

The event at Ground Zero – site of the collapsed Twin Towers of the World Trade Center – will mark the first time Mr McCain and Mr Obama have been together since they were formally nominated as presidential candidates at their parties’ just-completed national conventions.

The two agreed not to run television ads critical of each other on Thursday and Mr McCain’s campaign team said they would not run any ads.

With the parties’ nominating conventions over, the candidates have been gearing up for the last weeks of campaigning up to the 4 November election.

US campaign reaches final phase

Republicans can’t be trusted with the economy, Mr Obama says

US presidential rivals Barack Obama and John McCain have begun the final phase of their campaigns following their anointment by the party conventions.

Mr Obama, the Democratic candidate, seized on high unemployment figures to tell a rally that Republicans must be driven from the White House.

Republican John McCain promised to work to fix the economy.

Both candidates are focusing on key battleground states ahead of the presidential election in November.

Campaigning in the industrial north-east, Mr Obama criticized Mr McCain’s acceptance speech at the Republican convention on Thursday, citing the country’s economic woes.

“If you watched the Republican National Convention over the last three days, you wouldn’t know that we have the highest unemployment in five years,” Mr Obama told workers at a factory near Scranton, Pennsylvania, on Friday.

“They didn’t say a thing about what is going on with the middle class.”

They’re tough times in Wisconsin, they’re tough times in Ohio, tough times all over America John McCain

Government figures show that the jobless rate reached 6.1% in August.

Mr McCain told supporters in Wisconsin – another swing state – that the sagging economy had squeezed everyone in the country.

“These are tough times,” he said. “They’re tough times in Wisconsin, they’re tough times in Ohio, tough times all over America.”

But he promised that “change is coming”.

The candidates were gearing up for the last weeks of campaigning up to the 4 November election.

They used their respective party conventions to address vulnerabilities in their campaigns.

Mr McCain – who has a reputation as a maverick – tried to strike a balance between distancing himself from an unpopular presidency and rallying the party’s conservative base.

His selection of conservative Sarah Palin as a vice-presidential running mate helped rally supporters of President George W Bush.

A week earlier, Mr Obama – who needed to heal Democratic divisions after his primary election battle with Hillary Clinton – got a boost when her husband, former President Bill Clinton, gave him unqualified backing in his convention speech.

Palin takes battle to Democrats

Palin takes battle to Democrats

John McCain’s running mate, Sarah Palin, has made a stinging attack on Democratic presidential runner Barack Obama at the US Republican convention.

She gave her first major campaign speech to an enthusiastic crowd at the convention in St Paul, Minnesota.

Defending her small-town roots, she attacked Mr Obama as having talked of change, but done nothing of substance.

Mr McCain made a surprise appearance on stage, with her family, saying: “Don’t you think we made the right choice?”

The Arizona senator has been formally nominated as the party’s presidential candidate in a roll call vote by state delegations. He is expected to accept the nomination on Thursday.

I’ve learned quickly… , that if you’re not a member in good standing of the Washington elite, then some in the media consider a candidate unqualified for that reason alone Sarah Palin

In a speech designed to rally the party base, she spoke of her family, including her elder son, who is about to be deployed to Iraq in the US Army, and her younger son, who has Down’s Syndrome.

The mother-of-five highlighted her background as a small-town “average hockey mom” and stressed that she was not part of the “Washington elite”.

In a salvo directed at media commentators who have questioned her qualifications, she said she was “not going to Washington to seek their good opinion” but to serve the people.

Mrs Palin praised the “determination, resolve and sheer guts” of Mr McCain and said she was honoured to help him.

Mrs Palin also attacked Mr Obama’s “change agenda” and suggested he was more interested in idealism and “high-flown speech-making” than acting for “real Americans”.

“In politics, there are some candidates who use change to promote their careers,” she said.

I liked the parliamentary-style jabs at Obama BBC North America editor Justin Webb

“And then there are those, like John McCain, who use their careers to promote change.”

She also targeted Mr Obama’s experience as a community organiser and remarks he made earlier this year when he spoke of “bitter” working-class people “clinging to guns or religion”.

“I guess that a small-town mayor is sort of like a ‘community organizer’, except that you have actual responsibilities,” she said.

“I might add that in small towns, we don’t quite know what to make of a candidate who lavishes praise on working people when they are listening, and then talks about how bitterly they cling to their religion and guns when those people aren’t listening.”

Mrs Palin – who supports drilling for oil in Alaska’s Arctic National Wildlife Refuge – said that while drilling “will not solve all of America’s energy problems”, that is “no excuse to do nothing at all”.

Democrats under fire

Former Governors Mitt Romney and Mike Huckabee opened the night by hailing Mr McCain and attacking the Democrats.

Mr Romney, a one-time rival of Mr McCain for the Republican nomination, used his speech to hammer the Democrats over their “liberal” agenda.

“We have a prescription for every American who wants change in Washington – throw out the big government liberals and elect John McCain,” the former Massachusetts governor said.

He also lauded Mr McCain’s national security credentials, saying he was the presidential contender who would defeat “evil” radical Islam.

Mr Huckabee, also a former rival of Mr McCain, joked that he had hoped to be giving the speech on Thursday night – when Mr McCain will accept the party’s nomination to run for president in November’s election.

But, he said, he was delighted to be speaking for his second choice, Mr McCain – “a man with the character and stubborn kind of integrity that we need in a president”.

He defended Mrs Palin against criticism from the media, saying its coverage had been “tackier than a costume change at a Madonna concert”, and attacked the Democrats’ vice-presidential candidate Joe Biden.

You need to face your enemy in order to defeat them. John McCain will face this threat and bring victory to this country Rudy Giuliani

“I am so tired of hearing about her lack of experience. She got more votes running for mayor of Wasilla, Alaska, than Joe Biden got running for president of the United States,” he said, referring to Mr Biden’s performance in the Democratic primaries.

Former New York City Mayor Rudy Giuliani followed Mr Huckabee on stage, calling the 2008 presidential election a “turning point” for the people of the US.

He charged the Democrats with being in denial about the threat from terrorism and said Mr McCain had the foreign policy, national security and leadership experience that counted.

“The choice in this election comes down to substance over style,” he said. “John has been tested. Barack Obama has not. Tough times require strong leadership, and this is no time for on the job training.”

Vetting questions

The Alaska governor’s speech comes amid scrutiny of her record and after two days dominated by the news her daughter Bristol, 17, is pregnant.

Mrs Palin and her family, including Bristol and her boyfriend, greeted Mr McCain at the airport as he arrived in Minnesota on Wednesday.

Ahead of her address, senior McCain campaign adviser Steve Schmidt issued a statement saying that media questions over how thoroughly Mrs Palin was vetted should end.

It has also been revealed that an attorney has been hired to represent Mrs Palin in an Alaska state ethics investigation involving alleged abuse of power.

Mrs Palin told US network CNBC she had “nothing to hide”. Her deposition is expected to be scheduled soon.

There have also been reports that Mrs Palin sought special financial favors for her city and state – something the McCain campaign is against.

She was elected governor of Alaska in 2006 and before that was mayor of the small town of Wasilla, Alaska.
