Kenya's Supreme Court has confirmed Uhuru Kenyatta as the winner of the presidential election, dismissing a challenge by main rival Raila Odinga.
Mr Odinga, who had alleged irregularities in the poll earlier in March, says he respects the court's decision and wishes Mr Kenyatta well.
Chief Justice Willy Mutunga announced the decision on Saturday, saying the poll was free and fair.
The unanimous decision by the six judges means there are now no further obstacles to Mr Kenyatta, the son of the African nation's founding father Mzee Jomo Kenyatta, being sworn in on 9 April, the BBC reports.
But in July Mr Kenyatta and running mate William Ruto are due to face charges at the International Criminal Court of crimes against humanity in relation to violence that followed the last election in 2007. They deny the charges.
When the results were first announced earlier in March, Mr Kenyatta called it a triumph for democracy, but Raila Odinga didn't see it that way, saying the poll was marred by irregularities.
Official results show Mr Kenyatta beat Mr Odinga by 50.07% to 43.28%, avoiding a run-off by just 8100 votes.
Supporters of Mr Kenyatta took to the streets of central Nairobi, tooting their horns, blowing on vuvuzelas and chanting. Outside the courthouse, police used tear gas to chase away people protesting against the ruling.
There were also reports of tear gas being fired at stone-throwing youths in the western city of Kisumu, a stronghold of Mr Odinga, and the BBC reports there was an angry mood in the Nairobi slum of Kibera, with people chanting "no Raila no peace".
But Mr Odinga says he respects the court's decision and casting doubt on it would lead to political and economic uncertainty in Kenya.
