Harare - Zimbabwe's ruling party has sacked Robert Mugabe as its leader, as pressure intensifies for him to step down as president. Zanu-PF appointed ex-Vice-President Emmerson Mnangagwa, who was fired by Mr Mugabe two weeks ago, in his place. The party has given Mr Mugabe, 93, until 10:00 GMT on Monday to resign as president, or face impeachment. The military intervened last week, in an apparent attempt to block him from installing his wife as his successor. The first lady, Grace Mugabe, and several other senior officials have been expelled from the party altogether. Tens of thousands of Zimbabweans attended street protests on Saturday, demonstrating against the Mugabes. Mr Mugabe has also reportedly been meeting military leaders, according to Zimbabwe's The Herald. While no details of the talks have been released, photos posted by the newspaper show the two sides - which also met several days ago - shaking hands. Reports say cheering erupted when the decision to dismiss Mr Mugabe as party leader was announced. One senior official said: "It's the dawn of a new era. Mugabe can go farming." Zanu-PF's Central Committee also warned that impeachment proceedings would begin on Tuesday if Mr Mugabe did not step down as president by noon local time on Monday. Another party official said Mr Mnangagwa, who has since reportedly returned to Zimbabwe, had been nominated as the party's presidential candidate for the 2018 general elections.(FA)
