Former Finance Minister Trevor Manuel called on President Jacob Zuma to resign in an interview with Soweto TV. “A violation of the key oath of office of the Head of State, which I think is a deep crisis. I think it’s in all of our interests that the president actually steps aside," Manuel said. His call comes after ANC stalwarts Mathews Phosa and Ahmed Kathrada called on the president to step down.
