Crowds are gathering at a 60,000-seat stadium in Zimbabwe’s capital, Harare, to witness the swearing-in of Emmerson Mnangagwa as the country’s president.
It follows the dramatic departure of Robert Mugabe after 37 years of authoritarian rule.
The former vice-president’s dismissal earlier this month led the ruling Zanu-PF party and the army to intervene and force Mr Mugabe to quit.
Mr Mnangagwa, who had fled the country, returned from exile on Wednesday.
The opposition is urging Mr Mnangagwa, who has been part of the ruling elite, to end the “culture of corruption”.
