Guinea-Bissau's national electoral commission confirmed former Prime Minister Umaro Cissoko Embalo as the winner of the presidential ballot.

Wednesday's confirmation came after the Guinea-Bissau Supreme Court questioned the election results last week.

On Friday, the court called for a clarification of the tally hours after the electoral commission released the final results that showed Embalo's victory with 54% of votes cast versus Domingos Simoes Pereira's 46%.

"The Supreme Court ruling has been scrupulously followed," the commission said in a statement released on Wednesday. "All that remains to do is follow the swearing-in procedure."

Former Prime Minister and former army General Embalo had been hailed as the winner of last month's runoff vote. But runner-up and ruling party candidate Pereira had contested the results saying the election was marred by fraud.

There was no immediate reaction on Wednesday from both politicians to the commission's announcement.
