Lawyers representing Zimbabwe opposition party MDC Alliance and its leader Nelson Chamisa have arrived at the Constitutional Court in the capital, Harare, to file a challenge to President Emmerson Mnangagwa's election win.

Mr Chamisa says he has evidence to show that he was cheated out of the presidential election.

The court will have 14 days to make a ruling.

An organisation that monitors politics in Zimbabwe has shared pictures and a video of the legal team's arrival.
