There have been mixed signals from within the ANC about Zuma's fate, with delegations led by new ANC president Cyril Ramaphosa pressing that he is engaging with Zuma and ironing out a smooth transition - while secretary general Ace Magashule and deputy Jessie Duarte are adamant Zuma's early exit is not on the formal agenda.
The party's top six were in Limpopo to meet with traditional leaders, while also preparing to meet with President Jacob Zuma on Sunday.
ANC acting national communications manager Khusela Diko told the Sunday Times that she could not confirm whether the talks would include Zuma's resignation, but said that the NWC would discuss the upcoming motion of no confidence in Zuma, tabled by the EFF in Parliament, and the impeachment process.
The ANC did not say what had been decided at the meeting between Zuma and the party's "Top Six" leadership team at Zuma's residence in Pretoria, but it summoned its National Working Committee (NWC) to an urgent meeting on Monday afternoon.

Zuma has not said whether he will step down voluntarily before his second term as president ends next year. He reportedly said the meeting was not meant to humiliate Zuma.
"We want to ensure that there is stability in the country that is why we are meeting President Zuma".
He added that the best way to achieve this would be to go to Zuma and say "look we're not booting you out but we think we can work better this way".
