In a televised address to the nation late on Wednesday, the 75-year-old said he was a disciplined member of the ANC, to which he had dedicated his life.
“I fear no motion of no confidence or impeachment … I will continue to serve the people of South Africa and the ANC. I will dedicate my life to continuing to work for the execution of the policies of our organisation,” Zuma said.
“No life should be lost in my name. The ANC should never been divided in my name. I have therefore come to the decision to resign as president of the republic with immediate effect.”
The resignation ended an extraordinary day in South African politics, which had begun with a dawn raid on a business family at the centre of the recent corruption allegations levelled at Zuma.
