The military leader of Chad, Mahamat Idriss Deby Itno, has named a veteran opposition politician, Saleh Kebzabo, as the new prime minister as he seeks to stave off protests against continued army rule.
The appointment comes several days after a national forum confirmed General Deby as transitional president for the next two years and delayed promised elections.
Mr Kebzabo, 75, was a presidential candidate several times, standing against Gen Deby's father, Idriss Deby.
The general assumed power in April last year after his father was killed in battle against rebel forces.
Last month, the African Union appealed in vain for the military not to extend its rule beyond an agreed 18-month interim period.
