However, Raila Odinga urged his supporters to boycott the second vote because he said no reforms had been made to the electoral commission since the original poll.
Correspondents say the election dispute has left Kenya deeply divided.
About 50 people are reported to have been killed in violence since the August ballot.
Raila Odinga had promised to hold a “memorial rally” in another part of Nairobi to honor those killed during the four months of political upheaval since the August vote.
According to the opposition leader, Uhura Kenyatta was elected by “just a small section of the country”.
There were scenes of chaos outside Nairobi’s Kasarani sports stadium when people without seats tried to rush in and were driven back by police with tear gas, and on horseback.
Big screens had been promised so that tens of thousands of people could watch the ceremony from outside the stadium but no screens were provided, AFP reports.
Inside the stadium itself, foreign dignitaries took up their seats in a calm, good-humored atmosphere.
Spectators were treated to musical performances and a military parade.
Ethiopian PM Hailemariam Desalegn and Rwandan President Paul Kagame are among a number of African leaders attending. Israel’s PM Benjamin Netanyahu is also expected in Kenya’s capital but for an event later in the presidential palace, the Jerusalem Post reports.
On October 26, the polls opened at 06:00 with tens of thousands of police and other security staff deployed to protect voters and polling stations.
International observers have scaled down their missions for security reasons.
According to unconfirmed reports, police have fired live rounds into the air to disperse opposition supporters in the western city of Kisumu and the Kibera area of Nairobi. Tear gas has also been used.
After casting his vote in the town of Gatundu, Uhuru Kenyatta urged people to cast their ballots so the country could move on.
He said: “We’re tired as a country of electioneering. It’s time we moved forward.”
Uhuru Kenyatta also said most of Kenya was “calm and peaceful”.
VP William Ruto has now called on the commission to declare Uhuru Kenyatta president as a result of Raila Odinga’s announcement.
The election re-run was due to take place on October 26, but Raila Odinga said on October 10: “We have come to the conclusion that there is no intention on the part of the IEBC [electoral commission] to undertake any changes to its operations and personnel… All indications are that the election scheduled for 26 October will be worse than the previous one.”
As a result, Raila Odinga said, “considering the interests of the people of Kenya, the region and the world at large” it was best that he withdrew from the race.
His coalition party believes the election will have to be cancelled as a result of his withdrawal, allowing “adequate time to undertake the reforms necessary to conduct an election that is in strict conformity with the constitution, the relevant laws and the constitution”.
However, Uhuru Kenyatta, speaking at a rally in the southern town of Voi, said: “We have no problem going back to elections. We are sure we will get more votes than the last time.”
The result of Kenya’s presidential election has been annulled by the country’s Supreme Court after citing irregularities.
The court ordered a new election within 60 days.
The election commission had declared incumbent Uhuru Kenyatta the winner by a margin of 1.4 million votes.
His opponent, Raila Odinga, said the commission was “rotten” and demanded resignations and prosecutions.
President Uhuru Kenyatta said he would respect the court’s decision but also branded the judges “crooks”.
Other elections in Africa have been annulled or canceled but this appears to be the first time on the continent that an opposition court challenge against a presidential poll result has been successful.
Chief Justice David Maraga said the August 8 election had not been “conducted in accordance with the constitution” and declared it “invalid, null and void”.
He said the verdict was backed by four of the six Supreme Court judges.
The announcement drew cheers from opposition supporters both inside and outside the courtroom.
Justice David Maraga said the election commission had failed “to conduct the presidential election in a manner consistent with the dictates of the constitution”.
He said the commission had committed irregularities “in the transmission of results”, adding that the court would provide details in a full judgment within 21 days.
Dissenting judges said that the Nasa opposition alliance – which had petitioned the Supreme Court – failed to prove claims that the polls had been rigged.
The election sparked days of sporadic protests, in which at least 28 people were killed. The vote had raised fears of major political violence – as was the case after a disputed poll in 2007.
Raila Odinga, 72, said the ruling marked “a historic day for the people of Kenya and by extension for the people of the continent of Africa”.
He said: “It is now clear that the entire [electoral commission] is rotten.
“It is clear that the real election results were never shared with Kenyans. Someone must take responsibility.”
He added: “We won the elections and we are going to win them again.”
In a TV address, President Kenyatta said that it was “important to respect the rule of law even if you disagree with the Supreme Court ruling”.
He called for calm, saying: “Your neighbor will still be your neighbor, regardless of what has happened… My primary message today to every single Kenyan is peace. Let us be people of peace.”
Uhuru Kenyatta, 55, added: “We are ready to go back again to the people with the same agenda that we delivered to the people.”
The president was more combative later at a rally of supporters in a market in Nairobi.
He referred to Justice David Maraga and his fellow judges as wakora (crooks in Swahili), saying they had “decided to cancel the election”. He warned the chief justice that as the poll had been annulled he was now the president again, not president-elect.
“Do you understand me? Maraga should know that he is now dealing with the serving president,” the president said.
“We are keeping a close eye on them. But let us deal with the election first. We are not afraid.”
After the election, international monitors from the EU, the African Union and the US had said there was no major fraud on polling day and urged Raila Odinga to concede.
On September 1, Marietje Schaake, the head of the EU Observer Mission, said the court ruling represented “a historic day for Kenya and we have always said that people who feel aggrieved should seek the path of the courts”.
She said the monitors had at the time pointed to irregularities and encouraged the Kenyan authorities to deal with them.
Marietje Schaake said the monitors were awaiting the full details of the ruling.
Uhuru Kenyatta has been sworn in as Kenya’s president after winning elections against Raila Odinga back in March.
Dignitaries and tens of thousands of people witnessed the inauguration at a stadium in the capital, Nairobi.
Raila Odinga did not attend the ceremony after his attempt to overturn Uhuru Kenyatta’s victory in court failed.
Uhuru Kenyatta and his deputy, William Ruto, face charges at the International Criminal Court relating to post-election violence five years ago.
Uhuru Kenyatta has been sworn in as Kenya’s president after winning elections against Raila Odinga back in March
They were on opposite sides at the time and both deny the accusations.
Sudanese President Omar al-Bashir, who faces an ICC arrest warrant over the conflict in Darfur, was not in Nairobi for the inauguration.
Uhuru Kenyatta, 51, is the son of Kenya’s founding father, Jomo Kenyatta, and is heir to one of the largest fortunes in Kenya.
He served as deputy prime minister, minister for trade, and finance minister under outgoing President Mwai Kibaki
The crowd, waving Kenyan flags, burst into rapturous welcome as Uhuru Kenyatta took the oath of office, becoming Kenya’s youngest president.
In his inaugural address, Uhuru Kenyatta said he would govern for all Kenyans.
“We will leave no community behind… Where there’s disillusionment, we’ll restore hope,” he said.
The new government would abolish maternity fees in its first 100 days and children starting school next year would be given laptops, he added.
In an apparent reference to the ICC case against him, Uhuru Kenyatta said: “I assure you again that under my leadership, Kenya will strive to uphold our international obligations, so long as these are founded on the well-established principles of mutual respect and reciprocity.”
US and European diplomats attended the inauguration, despite warning before the election that they would have limited contact with Uhuru Kenyatta if he is voted into office.
Among the African leaders present for the inauguration were South Africa’s Jacob Zuma, Nigeria’s Goodluck Jonathan and Uganda’s Yoweri Museveni.
Yoweri Museveni told the cheering crowd that he wanted to applaud Kenyans for rejecting the “blackmail” of the ICC.
He supported the ICC when it was formed, but it was now being used by “arrogant actors” who were trying to “install leaders of their choice in Africa and eliminate those they don’t like”, he said.
Raila Odinga – the outgoing prime minister – did not attend the ceremony, choosing to be on holiday in South Africa instead.
Other senior members of his Coalition for Reforms and Democracy (CORD) party have also stayed away to signal their opposition to Uhuru Kenyatta’s presidency, correspondents say.
According to official results, Uhuru Kenyatta beat Raila Odinga by 50.07% to 43.28% in March, avoiding a run-off by just 8,100 votes.
Raila Odinga challenged the result, but said he would respect the Kenyan Supreme Court’s ruling in Uhuru Kenyatta’s favor.
The election was Kenya’s first after a disputed poll in 2007, which led to violence that left more than 1,200 people dead.
Uhuru Kenyatta is due to appear at the ICC for his trial in The Hague later this year, accused of crimes against humanity. He denies the charges.
Kenya is a party to the Rome Statute, the treaty which established the ICC in 2002.
But like most African countries, it has refused to enforce the ICC warrant for Omar al-Bashir’s arrest.
After Omar al-Bashir visited Kenya in 2010, a Kenyan court ruled that the government must arrest him if he returned, in line with its international obligations under the Rome Statute.
Uhuru Kenyatta has fairly won the country’s presidential election, Kenya’s Supreme Court has ruled today rejecting several petitions challenging the vote.
Chief Justice Willy Mutunga announced the decision, saying the poll was free and fair.
The appeal was lodged by PM Raila Odinga, Uhuru Kenyatta’s main rival in the presidential poll this month.
Kenya’s Supreme Court has upheld Uhuru Kenyatta’s presidential election victory
Official results said Uhuru Kenyatta beat Raila Odinga by 50.07% to 43.28%, avoiding a run-off by just 8,100 votes.
There is tight security at the Supreme Court. Violence after a disputed election in 2007 left more than 1,200 people dead.
The presidential, legislative and municipal elections held on March 4 were the first since the 2007 poll.
Uhuru Kenyatta and his running mate, William Ruto, are facing trial on charges of crimes against humanity at the International Criminal Court (ICC) for allegedly fuelling unrest after that election. They deny the charges.
There was tight security for the court decision, with all roads leading to the building closed.
Police chief David Kimaiyo warned on Friday that unrest would not be tolerated.
He said: “We have reports indicating that some parties have organized their supporters to converge outside the Supreme Court during delivery of the ruling, and we will not allow any such gatherings.
“There will be tight security in all parts of the country, we will not tolerate any form of violence.”
Outgoing President Mwai Kibaki has urged people to stay calm and accept the result, but much will depend on Kenyans’ faith in their newly reformed judiciary.
Lawyers for Raila Odinga said their petition to the Supreme Court included allegations of vote manipulation, as well as problems with the registration of voters and an electronic vote counting mechanism.
On Friday, the Supreme Court reviewed recounts from 22 polling stations. Both sides claimed that the recounts vindicated their position.
Uhuru Kenyatta has called the election, which was largely conducted peacefully, a “triumph of democracy”.
The Independent Electoral and Boundaries Commission (IEBC) has insisted that the vote was credible, despite technical failures with an electronic voter ID system and the vote counting mechanism.
International observers said the poll was largely free, fair and credible, and that the electoral commission had conducted its business in an open and transparent manner.
Kenya’s PM Raila Odinga has filed a Supreme Court appeal against Uhuru Kenyatta’s narrow victory in the recent presidential election’s first round.
Uhuru Kenyatta beat Raila Odinga comfortably by 50.7% to 43.28% on March 4, avoiding a run-off by only 8,100 votes.
However, Raila Odinga has accused the electoral authorities of manipulating the result.
Police fired tear gas to disperse about 100 supporters of his Coalition for Reforms and Democracy (Cord) who had gathered outside the Supreme Court.
The police had warned them that they would not be allowed to do so.
Some of the crowd were wearing t-shirts bearing slogans including “I support the petition” and “Democracy on trial”.
The presidential, legislative and municipal elections held 12 days ago were the first since the 2007 poll which set off ethnic and political violence in which more than 1,200 people were killed.
Uhuru Kenyatta and his running mate, William Ruto, are facing trial on charges of crimes against humanity at the International Criminal Court (ICC) for allegedly fuelling the unrest. They deny the charges.
Lawyers for Raila Odinga said their petition to the Supreme Court included allegations of vote manipulation, as well as problems with the registration of voters and an electronic vote counting mechanism.
“I have no hesitation whatsoever in lawfully challenging the election outcome,” Raila Odinga told reporters outside his offices in Nairobi.
“These failures dwarf anything Kenyans have ever witnessed in any previous election,” the prime minister added.
Raila Odinga has filed a Supreme Court appeal against Uhuru Kenyatta’s narrow victory in the recent presidential election’s first round
However, Raila Odinga urged his supporters not to resort to violence.“We cannot begin what is supposed to be a new era under a new constitution in the same old ways,” he added, referring to the charter adopted in 2010.
The Minister of Lands, James Orengo, a senior Cord official, said the party had a constitutional right to file the petition and a “strong case”.
“Expect a new election, and this time around no monkey-business. I think we’re going to win and win in the first round,” James Orengo told KTN TV.
“I can assure you that we have the evidence, and we have the will and the preparedness to prosecute the petition,” he added.
James Orengo nevertheless promised that Cord would respect the Supreme Court’s ruling if it went against the party, and urged Uhuru Kenyatta and his supporters to declare that they would do likewise.
In his acceptance speech last Saturday, Uhuru Kenyatta described the election as “free and fair” and a “triumph of democracy”.
The Independent Electoral and Boundaries Commission (IEBC) has also insisted that the vote was credible and that it is ready for any legal scrutiny.
International observers said the election was largely free, fair and credible, and that the electoral commission had conducted its business in an open and transparent manner.
Raila Odinga was the runner-up to Mwai Kibaki in the 2007 presidential election, which he also said was stolen.
Kenyan Deputy PM Uhuru Kenyatta appears to have won the presidential election by the tightest of margins as the provisional results indicate.
After all the votes were counted Uhuru Kenyatta had polled 50.03% of the vote, 4,109 votes over the threshold required for outright victory.
However, the official result is not expected before 11:00 on Saturday.
Rival candidate Raila Odinga is set to file a legal challenge if he loses.
One of Raila Odinga’s aides said the candidate had “no intention” of conceding defeat.
Salim Lone told the Daily Nation newspaper: “The level of the failures in the system makes it very difficult to believe it was a credible result, and if Uhuru is declared president, Raila will go to court.”
Both candidates have complained of irregularities during the course of the count, since Monday’s election.
Uhuru Kenyatta won 6,173,433 votes out of a total of 12,338,667, well ahead of the prime minister, who polled 5,340,546 – or 43.28% of the vote.
Uhuru Kenyatta’s Jubilee Coalition party said it was “proud and honored for the trust” bestowed on it, adding that it had taken a message to the people and that “we are grateful to the people of Kenya for accepting this message”.
Early on Saturday, small groups of Kenyatta supporters celebrated in Nairobi, hooting car horns and singing.
If Uhuru Kenyatta is confirmed by Kenya’s Independent Electoral and Boundaries Commission (IEBC), he could face difficult relations with Western countries.
He faces trial at the International Criminal Court (ICC) in The Hague in July for crimes against humanity.
He is accused of fuelling communal violence after the 2007 election that saw more than 1,000 people killed and 600,000 forced from their homes.
Uhuru Kenyatta’s running mate, William Ruto, also faces similar charges.
Both men deny the accusations.
Kenyan Deputy PM Uhuru Kenyatta appears to have won the presidential election by the tightest of margins as the provisional results indicate
The ICC has agreed to postpone William Ruto’s trial by a month until May after his lawyers complained of not having enough time to prepare his defence.
Countries including the US and UK have hinted that his election as president would have consequences for their relations with the Nairobi government – comments which have been dismissed in Nairobi as unwanted foreign interference in domestic matters.
Kenya’s new electronic voting system was designed to eliminate the chance of vote-rigging and with it any risk of a repeat of the post-poll violence of 2007.
But the count has been plagued with technical glitches, including a programming error that led to the number of rejected votes being multiplied by a factor of eight. By Wednesday, the electronic system was abandoned and the count restarted by hand.
According to Kenya’s election rules, the winner needs to poll more than 50% of the vote to avoid a second round run-off next month.
If the election commission confirms that Uhuru Kenyatta has crossed the 50% threshold by such a narrow margin, then Raila Odinga’s officials say he will challenge the outcome.
The prime minister’s Cord alliance had earlier complained that votes from 11 constituencies were missing, in effect leaving him more than 250,000 votes short.
Both men passed a second condition needed for victory – at least 25% of the vote in more than half of the 47 counties.
The ballot count in Kenya’s presidential elections has been rigged, says the running mate of Prime Minister Raila Odinga, who is trailing behind his rival, Uhuru Kenyatta.
“We have evidence the results we have received have been doctored,” said Raila Odinga’s running mate Kalonzo Musyoka.
He said the vote count should be stopped but added that his comments were not a call for protest.
Counting has been severely delayed after the electronic system crashed.
Following the latest allegation, the Independent Electoral and Boundaries Commission (IEBC) is holding a closed-door meeting with various high commissioners and ambassadors.
The chairman of the IEBC is due to address journalists later on Thursday.
More than 1,000 people were killed in the violence which broke out in 2007-08 after Raila Odinga claimed he had been cheated of victory by supporters of President Mwai Kibaki, who is stepping down after two terms in office.
Uhuru Kenyatta, who backed Mwai Kibaki, is due to stand trial at the International Criminal Court (ICC) next month, accused of organizing attacks on members of ethnic groups seen as supporters of Raila Odinga. He denies the charges.
Kalonzo Musyoka said the failure of the electronic vote transmission system earlier this week had allowed results to be rigged.
“We as a coalition take the position the national vote-tallying process lacks integrity and has to be stopped and re-started using primary documents from the polling stations,” he said on Thursday.
But Kalonzo Musyoka also called on Kenyans to remain calm.
“It is not a call to mass action. We are committed as a coalition to the principle of the rule of law.”
The ballot count in Kenya’s presidential elections has been rigged, says the running mate of Prime Minister Raila Odinga
Meanwhile, senior members of Raila Odinga’s coalition have given further details about their allegations, saying that the number of ballots counted exceeded that of votes cast.
The long delays, and these new accusations are increasing the tension surrounding the polls.
However, until they see comprehensive evidence, many Kenyans will remain skeptical.
Following glitches with hi-tech voting and counting systems, the vote-tallying process was started again from scratch, and by hand, on Wednesday.
Results were only being announced after the ballots had been physically delivered to election headquarters in Nairobi, rather than being filed electronically.
The latest figures indicate Uhuru Kenyatta has maintained his lead over Raila Odinga, with 2.5 million (53%) votes to 1.9 million (42%) – as originally indicated.
However, the new tally shows that the number of rejected ballots, which have become a major bone contention, has sharply come down.
In the initial count, some 300,000 votes – about 6% – were disqualified for various reasons.
But according to latest official results, this figure has now come down to about 40,000. While the reason for the drop remains unclear, some observers said that election officials were being too strict first time round.
Uhuru Kenyatta’s Jubilee coalition has rejected calls for some of these ballots to be included, as requested by Raila Odinga’s allies.
Counting the rejected votes would greatly add to the number needed for a candidate to break the 50% threshold for a first-round win and increase the prospect of a runoff due within a month.
The push for these ballots’ inclusion was motivated by a “sinister and suspect logic”, said Charity Ngilu, a senior member of Uhuru Kenyatta’s coalition.
The camp also accused the British High Commissioner in Kenya of “canvassing to have rejected votes tallied” in an attempt to deny Uhuru Kenyatta outright victory in Monday’s vote.
The UK Foreign Office said claims of British interference were “entirely false and misleading”.
Correspondents say one of the reasons for the many rejected votes is that Kenyans had, for the first time, six ballot papers to fill in, which may have caused confusion.
The winning candidate must get more than 50% of the total votes cast and at least 25% of votes in half of the 47 counties. The latter was a requirement introduced in the new constitution to make sure the new president wins with wide support, rather than only with the backing of voters in his regional and ethnic strongholds.
If there is no clear winner, a second round of voting will take place, probably on April 11.

Kenya is voting in an election that observers describe as the most important in the country’s history.
It is the first time a vote has taken place under Kenyan new constitution, designed to prevent a repeat of violence that followed the 2007 polls.
More than 1,000 people died in widespread ethnic violence when supporters of rival candidates clashed.
Despite appeals for calm, at least four police officers died when they were attacked near Mombasa on Monday.
At least six other people – including several attackers – are also reported to have died in the assault in the early hours in Changamwe, half an hour’s drive from the centre of Mombasa.
Reports from around the country suggested long lines of voters were forming before polling stations opened.
Some technical difficulties were reported with newly instituted biometric voting kits – designed to counter claims of vote-rigging and long delays in announcing poll results that were partly blamed for the violence last time.
Kenyans will choose a president, members of parliament and senators, county governors and members of 47 county assemblies.
Eight presidential candidates are standing but it is essentially a two-horse race pitting Prime Minister Raila Odinga against Deputy Prime Minister Uhuru Kenyatta.
Some observers say they are particularly concerned about violence erupting should neither of the two frontrunners poll more than 50% – in which case the vote will go to a run-off, probably on April 11.
Uhuru Kenyatta, son of Kenya’s founding father Jomo Kenyatta, is due to stand trial at the International Criminal Court for his alleged role in orchestrating the violence five years ago.
His running mate, William Ruto, has also been indicted by the court. Both men deny any wrongdoing.
Kenya is voting in an election that observers describe as the most important in the country’s history
The post-election violence of 2007-8 broke out after Raila Odinga claimed he had been cheated of victory by supporters of President Mwai Kibaki.
Supporters of the rival candidates, from different ethnic groups, took up arms against each other.
Raila Odinga later joined a government of national unity under a peace deal.
In the run-up to Monday’s vote, President Mwai Kibaki – who is not seeking re-election – urged Kenyans to vote peacefully and for the losers to accept defeat.
“Cast your vote and keep the peace,” he said in a televised address to the nation on Friday.
“Let us send a clear message to the world that our democracy has come of age. A peaceful vote is a vote for a secure, prosperous and stable Kenya.”
Candidates have also promised to respect the result and urged their supporters to refrain from violence.
Clerics across Kenya also gave sermons dedicated to peace on Sunday.
The police, however, have warned of conspiracies to cause chaos – in Nairobi and elsewhere – and have made it clear that violence will not be tolerated.
Security is being stepped up with some 99,000 police officers being deployed around the country, at polling stations and vote-counting centres.
The polling stations are open from 06:00 to 17:00 local time.
Presidential candidates must secure support from across the country to be declared the winner, so they cannot just rely on support from their ethnic groups, as has been the case in previous elections.
Official results will be announced by March 11 by the electoral commission.
