The Gabonese Democratic Party (PDG) looks to have won the first rounds of the legislative election by a landslide.
‘We have observed what looks like a landslide in favour of the [ruling] majority,’ presidential spokesman Ike Ngouoni said on Sunday, citing results posted publicly at voting stations.
The PDG won 80 of the 143 seats in the national parliament, he said.
Ngouoni said turnout was ‘relatively weak.’
The presidential spokesman says definitive results will be announced later on Monday.
Some opposition candidates and witnesses who spoke to the AFP news agency at polling stations alleged voting irregularities.
They said voting papers had gone missing, there had been attempts to buy votes, and opposition representatives had been denied access.
Voting took place in the oil-rich West African country on Saturday in a long-delayed legislative and municipal election, the first poll to be held since a presidential election two years ago was marred by deadly violence and fraud allegations.
President Bongo’s key rival, Jean Ping, boycotted the election, but most opposition groups took part.
Gabon has been ruled by the same political dynasty for over half a century. President Ali Bongo replaced his father Omar Bongo, who ruled the country for over three decades until his death.
