Opposition candidate Joseph Boakai has maintained a slim lead in the Liberian presidential election after official results from more than 99% of polling stations were announced.

The 78-year-old political veteran has 50.89% of the votes, while incumbent President George Weah has 49.11%.

That represents a lead of more than 28,000 votes, with nearly all the ballots accounted for.

The latest results have sparked celebrations in the capital, Monrovia.

Mr Boakai's supporters have been gathering at his party's headquarters in the city, convinced that he has won the election.

They have been shouting for President Weah, who has served one term, to go - and chanting "we beat the Buga dancer", referring to a song that became associated with his campaign.

There have been no formal statements from either of the candidates.
