Kenya presidential poll result 'will be challenged'

Kenya's Deputy Prime Minister Uhuru Kenyatta appears to have won the presidential election by the tightest of margins, provisional results indicate.

After all the votes were counted he had polled 50.03% of the vote, 4,109 votes over the threshold required for outright victory.

The BBC's James Copnall in Nairobi said there were likely to be legal challenges following the announcement of the result.
