Just hours after Zimbabwe President Robert Mugabe had apparently agreed to resign, the 93-year-old leader declined to back down in a speech Sunday night on national television. The move came after he was ousted as leader of the country’s ruling party, Zanu-PF. Emmerson Mnangagwa, the former vice president whom Mugabe forced out two weeks ago, has been named its leader. After firing Mnangagwa, Mugabe tried to name his wife Grace as vice president, but not before the military stepped in. Grace Mugabe has been sacked from the party, too. The Mugabes have remained under house arrest as the military takes control of key parts of the government. Mugabe was given until Monday at noon to resign as president—a position he has held since 1987—or face impeachment.
