Zimbabwe's Mugabe promotes wife but leaves successor vacuum

Ninety-year-old Zimbabwean President Robert Mugabe promoted his wife to the top ranks of his ZANU-PF party on Saturday but delayed filling vacant senior posts, prolonging anxiety over his lack of successor.

Africa's oldest head of state and the only leader Zimbabwe has known since independence from Britain in 1980 was elected unopposed at the five-yearly ZANU-PF meeting, putting him on track to contest the 2018 presidential elections, when he will be 94.
