South African President Jacob Zuma is under growing pressure to step down following talks with senior members of his ANC party on Sunday.
Details of the talks were not revealed but party leaders are to hold an emergency meeting on Monday.
Mr Zuma, who faces corruption allegations, was replaced as ANC leader by Cyril Ramaphosa in December.
Analysts say party chiefs want to avoid a power struggle that could split the ANC before elections next year.
They are expected to begin the process to remove President Zuma through a formal recall or by introducing a motion in parliament.
