The ANC would not reveal whether it would divorce the EFF in its coalition agreement in Ekurhuleni after a physical altercation between the two parties at council last week.
In a press briefing on Tuesday, the ANC said it would not "stay for the sake of staying" in its testy relationship with the EFF.
"We are prepared for the worst. The ANC is prepared for any eventuality," said the deputy chairperson of the ANC in Ekurhuleni, Jongisizwe Dlabathi.
