South African President Cyril Ramaphosa is to repay $35,000 (£27,300) given to his leadership campaign by a firm accused of corruption.

The donor, a firm called Bosasa, has won lucrative government contracts but is under investigation.

Mr Ramaphosa initially told MPs the money had been paid to his son, Andile, for consultancy work for Bosasa.

By later admitting it was a donation, he undermined his own anti-corruption fight, the BBC's Will Ross reports.

The controversy is a setback for a president who has vowed to fight corruption, our Africa editor adds. Mr Ramaphosa also ordered a review of all payments to his campaign for the leadership of the African National Congress (ANC). (BBC)
