A timeline of developments since the ousting of Robert Mugabe in Zimbabwe last November to the rejection by the opposition of the election victory of his successor Emmerson Mnangagwa. Mugabe out after 37 yearsTension builds following Mugabe's sacking of Emmerson Mnangagwa as his vice president in early November 2017, a move seen as positioning the veteran's president's wife to become his successor.Army tanks take up positions around the capital overnight November 14-15 and Mugabe is put under effective house arrest.Four days later the ruling Zanu-PF party sacks him as leader and expels his wife. On November 21 the 93-year-old Mugabe bows to pressure to quit and ends his 37-year grip on power.New president pledges polls On November 24 Mnangagwa is sworn in as president, promising that elections due in 2018 will go ahead.In February 2018 veteran opposition leader Morgan Tsvangirai dies of cancer; his Movement for Democratic Change (MDC) picks former youth activist Nelson Chamisa to lead it into the election set for July 30.A record 23 presidential candidates are in June cleared to stand.On June 23 a bomb explodes as Mnangagwa leaves the podium at a Zanu-PF campaign rally in the opposition stronghold city of Bulawayo. He escapes unharmed but dozens of people are injured and two of his bodyguards are killed.Historic vote On the eve of the vote, Mugabe holds a surprise press conference at his home at which he stuns observers and calls for voters to reject the Zanu-PF, his former party.He even hints that he could vote for Chamisa.Voting on July 30 takes place in a peaceful atmosphere. Long lines form from the early morning outside polling stations and turnout is estimated at around 75 percent.The next day, as vote counting is under way, Chamisa says that he is "winning resoundingly"."We are ready to form the next government," he says.The government warns candidates they face prosecution and jail for prematurely announcing results.The much-criticised election authority meanwhile declares there has been no rigging, after the opposition repeatedly alleges the vote process was flawed.Violence erupts On August 1 the election commission announces that Zanu-PF has won most of the seats in parliament. It does not give the results for the presidential vote.The opposition cries foul, alleging fraud, and EU observers say the elections were held on an "un-level playing field".Opposition protestors take to the streets of Harare, burning tyres and pulling down street signs.Soldiers arrive and fire live rounds on opposition activists. At least six people are killed.As international condemnation pours in, the government warns it will "not tolerate" further unrest.Mnangagwa declared winner In the early hours of August 3, the electoral commission declares Mnangagwa the winner with 50.8% of the vote - just enough to avoid a run-off against Chamisa, who scored 44.3%.The opposition rejects the results and says it will challenge them in court.'Fraudulent', 'illegitimate'On August 3 Chamisa insists that he won the election, rejecting the results as "fraudulent, illegal, illegitimate" and vowing to challenge them in court."We will pursue all means necessary, legal, constitutional, to make sure we protect the people's vote," he says. Mnangagwa defends a "free, fair and credible election".
