Provisional results in Kenya give Deputy Prime Minister Uhuru Kenyatta a razor-thin victory in Monday's presidential election.
The early results say Kenyatta won with 50.03 percent of the vote.
Getting more than 50 percent of the vote is critical to avoid a runoff election. Kenyatta appears to have achieved that margin by just 4,100 votes out of a total 12.3 million cast.
An advisor to Kenyan Prime Minister Raila Odinga, who is in second place with just over 43 percent of the vote, said Saturday his candidate has no plans to concede the election.
On Thursday, Odinga's running mate Kalonzo Musyoka said some results have been "doctored." Election commission chairman Hassan denied the allegation.
The commission has not yet finalized the results and says it will announce the official tally on Saturday.
Monday's vote was the first since Kenya's 2007 election which led to weeks of violence. More than 1,100 people were killed and 600,000 displaced after that disputed election.
In another development, the International Criminal Court has delayed the trial for Kenyatta's running mate, William Ruto, from April 10 to May 28.
Both Ruto and Kenyatta are charged with helping to orchestrate Kenya's post-election violence in 2007 and 2008. On Thursday, the ICC postponed Mr. Kenyatta's trial from April until July.
The vote counting for Monday's election has been slowed since an electronic reporting system failed earlier this week.
Despite the vote-counting problems, international observers have described Monday's vote in Kenya as transparent and credible.
Both Kenyatta and Odinga have promised to respect the result of this year's vote.
