Gambian President-elect Adama Barrow 'to declare himself president'

The Gambia's President-elect Adama Barrow has told the BBC that he will declare himself president on 18 January if Yahya Jammeh does not step down.

President Jammeh wants the election annulled and a new vote run by a "God-fearing" electoral commission.

However the UN has urged him to step down and said he could face sanctions if he clings to power.
