Gabon’s incumbent president, Ali Bongo, won a third term in the presidential election with 64.27% of the vote, the Gabonese election centre said on Wednesday, after a delay-plagued general election that the opposition denounced as fraudulent.
His overthrow would end his family’s 53-year hold on power in Gabon.
Announcing the result in the early hours, the elections head, Michel Stephane Bonda, said Bongo’s main challenger, Albert Ondo Ossa, came second with 30.77%. Bongo’s team rejected Ondo Ossa’s allegations of electoral irregularities.Tensions have run high amid fears of unrest after Saturday’s presidential, parliamentary and legislative vote, which saw Bongo seeking to extend his family’s 56-year grip on power while the opposition pushed for change in the oil-rich but poverty-stricken central African nation.
