KINSHASA (Reuters) - Losing Democratic Republic of Congo presidential candidate Martin Fayulu said on Friday he would challenge the election results in country’s highest court on Saturday at 9 a.m. (0800 GMT).

The national electoral commission on Thursday declared another opposition leader, Felix Tshisekedi, the winner of the Dec. 30 election, but Fayulu’s campaign says its tallies show that Fayulu won a landslide victory.
