Robert Mugabe resigned as Zimbabwe’s president on Tuesday. The 93 year old was the world’s oldest ruler and put an end to his decades in power after a military coup which happened last week. Mugabe wrote a letter saying that he was quitting “with immediate effect”. The ZANU-PF party has removed his name as leader and put Emmerson Mnangagwa, Mugabes former Vice-President, in his place. A ZANU-PF official told The Associated Press that Mnangagwa would take over within 48 hours.
