Youssouf Bakayoko, the head of the commission, announced today that President Alassane Ouattara earned 83 per cent of the October 25 vote.
He needed more than 50 per cent to avoid a runoff. The closest opposition candidate, Pascal Affi N'Guessan, got 9 per cent.
The presidential vote was the first since the 2010 contest in which Ouattara defeated then-President Laurent Gbagbo, whose refusal to step aside sparked months of violence that killed thousands.
Ouattara campaigned on the West African country's economic rebound and security gains during his tenure, though critics say he has failed to foster reconciliation or reduce poverty.
