South Africa’s embattled President Jacob Zuma says he has done nothing wrong and sees no reason to stand down.

Mr Zuma spoke after the ruling African National Congress (ANC) gave him an ultimatum to resign by the end of the day or face a parliamentary vote of no confidence on Thursday.

The 75-year-old has come under increasing pressure to resign amid numerous allegations of corruption.

But he said the ANC had failed to explain why he had been recalled.

In a lengthy, unannounced, interview with national broadcaster SABC, Mr Zuma made no reference to the early morning police raids and arrests at the home of his close associates, the wealthy, Indian-born Gupta family.

The Guptas have been accused of using their close friendship with the president to wield enormous political influence. Both parties deny all allegations of wrongdoing.
