PRETORIA - Former president Jacob Zuma addressed the nation from the Union Buildings in Pretoria on Wednesday night.
In a 30-minute national television address, Zuma said he had "come to the decision to resign as president of the Republic with immediate effect".
"I have only asked my party to articulate my transgressions and the reason for its immediate instruction that I vacate office," he said.

In an earlier TV interview on Wednesday, he said he had received "very unfair" treatment from the party he joined in 1959 and in which he had fought for decades against apartheid white-minority rule.
He said he was angered over "the manner in which the decision is being implemented... I don't agree as there is no evidence of if I have done anything wrong."
