Zimbabwe's President Emmerson Mnangagwa is set to be sworn in for a second term in office.

Official results gave him close to 53% of the vote in a presidential election which international observers said fell short of democratic standards.

His Zanu-PF party won close to two-thirds of the parliamentary vote.

Mr Mnangagwa’s main rival Nelson Chamisa has called for fresh elections.

He has until Monday to ask the court to overturn the results.

The red carpet has been rolled out and several heads of state have confirmed that they will attend Mr Mnangagwa’s inauguration.

The government is confident it will go ahead as planned.

But an official told the BBC that if the opposition lodged their court application before the ceremony, it could be called off.

Mr Chamisa's Citizens’ Coalition for Change has rejected Mr Mnangagwa’s election win as fraudulent – but hasn’t officially confirmed whether it will go to court.

International observers' harsh criticism of his election win is likely to hinder Mr Mnangagwa's plans for greater international re-engagement and an economic turn-around.

But the attendance of some regional leaders is likely to give him a semblance of the legitimacy that he seeks.
