DAR ES SALAAM - Tanzania's President John Magufuli on Thursday appointed a former junior minister as the country's new prime minister, with a cabinet expected to be formed in coming days.

The surprise choice of Majaliwa Kassim Majaliwa, 54, who served as deputy local government minister in the previous government, is the biggest decision taken by Magufuli since he assumed office on Nov. 5.
