A top official of Zimbabwe's ruling Zanu-PF party has shared a video of the party's lawyers failing to submit court papers to defend the election of Emmerson Mnangagwa as president.

The constitutional court was closed, presumably because the country was marking Heroes Day.

The opposition MDC Alliance alleges that the ruling party stole the election, but Mr Mnangagwa has said that he won fairly.

The court has 14 working days to decide the case.
