Zimbabweans are voting in their first election without Robert Mugabe on the ballot, a contest that could bring international legitimacy and investment or signal more stagnation if the vote is seriously flawed.
About 5.5 million people are registered to vote on Monday in this southern African nation anxious for change after decades of economic paralysis and the nearly four-decade rule of the 94-year-old Mugabe.
Long lines of voters are waiting outside some polling stations. Thousands of election monitors are in the country to observe a process that the opposition says is biased against them.
The two main contenders are 75-year-old President Emmerson Mnangagwa, a former deputy president who took over from Mugabe last year, and Nelson Chamisa, who became head of the main opposition party just a few months ago.
