Zimbabwe presidential election too close to call: poll

JOHANNESBURG (Reuters) - Zimbabwe's July 30 presidential election will provide no clear winner, with 40 percent of voters choosing President Emmerson Mnangagwa and 37 percent his opponent, Nelson Chamisa, according to an Afrobarometer poll released on Friday. The poll of 2,400 voting-age adults conducted between June 25 and July 6 found 20 percent of people would not disclose their choice. If no candidate receives more than 50 percent of the vote there will be a runoff on Sept. 8. (Reporting by Joe Brock; Editing by Ed Cropley)
