Uhuru Kenyatta won Kenya's deeply divisive presidential election re-run after winning 98.2 percent of the votes cast, the official results showed Monday.

In Thursday's protest-hit election, Kenyatta won 7,483,895 votes compared to 73,228 for his closest rival Raila Odinga, who had boycotted the vote. 

Turnout was just 38.84 percent. 

The election commission said on Monday declared the repeat presidential poll free and fair, despite opposition complaints over the vote that led to it boycotting the process.

"I’m satisfied that we were able to meet these conditions that have enabled the commission to deliver ... a free, fair and credible election," Wafula Chebukati, chairman of the commission, said.
