Benin's electoral commission said the party won 28 seats in the 109-member parliament.

It would be the first time its members have been represented in the chamber in four years.

But a party spokesman accused the commission of falsifying results in order to minimise the opposition's parliamentary representation.

Allies of President Patrice Talon secured 81 seats in the vote.

Final results are expected later this week.

Benin's opposition was in effect barred from running in the 2019 legislative elections with most of Mr Talon's opponents jailed or exiled.
