Gabon's constitutional court has upheld Ali Ben Bongo's win in the August presidential election.
The West African nation's top court Monday rejected all opposition challenges alleging massive fraud. Its decision came after it ordered a recount of the ballots, which was finished last week.
Official results gave Mr. Bongo 42 percent of the vote.
Nine opposition candidates challenged the results. They included the second- and third-place finishers Mba Obame and Pierre Mamboundou, who each got about 25 percent of the vote.
Most electoral observers believe the vote was fair, despite some irregularities.
Mr. Bongo is the son of Omar Bongo, who ruled Gabon for more than 40 years before his death in June.
