Kenya’s veteran opposition leader Raila Odinga has filed a challenge to the results of this month’s presidential election in the Supreme Court.

“What we did this morning is to file the online copy,” Mr Odinga’s lawyer Daniel Maanzo told a Kenyan television channel on Monday. “After today, there will be four days for the other parties to reply.”

The seven judges at Kenya’s Supreme Court will have 14 days to make a ruling.

Last week, Deputy President William Ruto won Kenya’s elections by 50.49 per cent of the votes over Mr Odinga’s 48.85 per cent, per official results announced by Wafula Chebukatu. 

The results, monitored live by Kenya’s Independent Electoral and Boundaries Commission, were announced after a week of counting. 

Mr Odinga, who had received the backing of outgoing President Uhuru Kenyatta, rejected the election results, calling the election a “travesty.”

The deputy chairperson of the electoral board, Juliana Cherera, and three other election commissioners dissented, saying the tallying of results had not been transparent.

This is Mr Odinga’s fifth attempt at the presidency. 

In 2017, the Supreme Court overturned the election result and ordered a rerun, which Mr Odinga boycotted, saying he had no faith in the election commission.
