Liberia election run-off: Ex-footballer up against vice-president
Liberians are to choose a new president in a run-off vote between Vice-President Joseph Boakai and former international footballer George Weah.
Mr Weah, 51, won the first round, but did not secure the required 50% of the vote for an outright victory.
Legal challenges delayed the vote to replace Ellen Johnson Sirleaf, Africa’s first elected female president.
Liberia, which was founded by freed US slaves in the 19th Century, has not had a smooth transfer of power in 73 years.
Polls across Liberia will open at 08:00 GMT and close at 18:00.
More than two million people are eligible to cast their ballots.
Who are the contenders?
Mr Boakai, 73, has been the Liberian vice-president for 12 years but does not seem to enjoy the support of his boss, the BBC’s Umaru Fofana reports from the capital, Monrovia.
The candidate has described himself as being like a limousine idly parked in a garage all these years, who is now ready to hit the road.
Meanwhile, Mr Weah, the former world footballer of the year, is hoping for third time lucky.
He defeated Ms Johnson-Sirleaf in the first round in 2005 but lost to her in the subsequent run-off. In the following election, when he ran as a presidential running mate, his coalition boycotted the run-off, citing irregularities.
Why was the vote delayed?
A representative for the opposition Liberty Party, Charles Brumskine, who came third in October’s first round, challenged the result saying it had been marred by “massive fraud and irregularities”.
But earlier this month the Supreme Court ruled that evidence of fraud was insufficient to merit a re-run of the opening round.
The verdict meant that the run-off – which had initially been set for 7 November – could go ahead.
Why is the election important?
This will be the first time for many generations in Liberia to witness a transfer of power from one elected leader to another, our correspondent says.
Outgoing President Sirleaf has praised a violence-free electoral process, saying that “the ballot box has replaced bullets and electoral disputes are settled through the courts”.
Ms Sirleaf took office in 2006, after her predecessor, Charles Taylor, was forced out by rebels in 2003, ending a long civil war.
Taylor is currently serving a 50-year prison sentence in the UK for war crimes related to the conflict in neighbouring Sierra Leone.
The results of the run-off are due to be announced within four days.
