Zambia’s main opposition party has alleged fraud in Thursday’s presidential vote and called for a recount of votes in the capital Lusaka.
The UPND party, led by Hakainde Hichilema, has withdrawn from the ballot verification process.
President Edgar Lungu, of the governing PF party, holds a slim lead over his rival Mr Hichilema, with votes counted in more than 80% of constituencies.
Mr Lungu has called for calm and for the will of the people to be respected.
Mr Lungu won the last election by less than 28,000 votes.
