Embattled South African president Jacob Zuma has said he is resigning "with immediate effect".
In a press conference, Mr Zuma said he did not "fear exiting political office" after facing a no-confidence motion from his party, the African National Congress (ANC).
He said: "I have therefore come to the decision to resign as president of the Republic with immediate effect, even though I disagree with the decision of the leadership of my organisation.
"I have always been a disciplined member of the ANC.
"As I leave, I will continue to serve the people of South Africa as well as the ANC, the organisation I have served all of my life in it."
Sky News' Africa correspondent John Sparks said Mr Zuma had become increasingly unpopular in South Africa after facing a string of corruption allegations.
