Yesterday representatives from the ACDP, AIC, COPE, DA, EFF, FF+, PAC and UDM met in Cape Town to discuss the removal of Jacob Zuma as President of the Republic of South Africa.
After almost 10 hours of heated debate, Ramaphosa and a key ally of Zuma left the meeting to drive to the President's official residence to deliver an ultimatum: stand down or face "recall", a technical term for the process of forcing an ANC official to leave their post.
"We are not treating Jacob Zuma as a leader who is defiant". If he refuses to resign, the matter could go to parliament for a vote on a motion of no confidence.
Zuma pioneered South Africa's entry to join the Brazil, Russia, India and China grouping. Zuma, 75, has been in power for over a decade; he is being forced out over a corruption scandal related to a 1990s arms deal.
He told Mr Zuma, whose term as head of state is not up until next year, that if he does not resign by midnight tonight he will be sacked by parliament where the ANC has a 62pc majority.
Ramaphosa narrowly defeated Zuma's ex-wife and preferred successor, Nkosazana Dlamini-Zuma, in the leadership vote, forcing him to tread carefully in handling Zuma for fear of deepening the rifts in the party a year ahead of an election.
Opposition parties were pushing that their motion be tabled first, which would force ANC MPs to vote Zuma out with and through the initiative of their opposition counterparts.
Zuma was scheduled to stand down after serving the maximum two terms after coming to power in 2009.
"One of Zuma's sons works for the Guptas, as do the children of other high ranking officials".
