We're expecting the Nigerian President Muhammadu Buhari to arrive in The Gambia today in an attempt to persuade President Yahya Jammeh to step down after he lost the election.
Mr Buhari is expected to be joined by Liberian leader Ellen Johnson-Sirleaf, Sierra Leone's Ernest Bai Koroma and Ghana's John Mahama, who himself lost an election last week and has said he will step down as president next month.
