The Gambia’s president-elect Adama Barrow is to remain in Senegal until his planned inauguration on Thursday, state media in Senegal say.
APC said the move was requested by West African leaders after a Mali summit.
President Yahya Jammeh, who initially admitted election defeat, says he will not step down until May, when the supreme court can hear his challenge.
Regional bloc Ecowas wants the UN to approve military action if Mr Barrow’s inauguration on Thursday is blocked.
