JOHANNESBURG - Finance Minister Malusi Gigaba says President Jacob Zuma must resign on Wednesday or face a no-confidence motion in Parliament.
Gibaga told CNN on Tuesday night that Zuma must do the right thing.
The ANC's highest decision-making body has recalled the President.
Gigaba said the party will be forced to remove Zuma through a parliamentary process if he continues to defy the party.
The ANC caucus is meeting in Parliament to discuss the decision.
Zuma is expected to address the nation on Wednesday.
