The naming of a new prime minister has breathed fresh life into divided Ivory Coast's faltering peace process but squabbling could soon arise over how much authority he should have, analysts said on Monday. As part of an African Union peace formula to reunite Ivory Coast, Charles Konan Banny, 63, governor of West Africa's central bank, was named prime minister late on Sunday. The U.N.-backed deal gives Banny powers to carry out disarmament and electoral reforms, meant to lead to presidential elections by the end of October next year.
