1) We are told negotiations are happening between the ANC President and the President of the country about a "transition". But what are they negotiating about? Can't (and should not) negotiate about immunity as that cannot legally be given.
2) Now, in a democracy, it is a bit odd that we are told there is this negotiation but we are not told what the negotiation is about or why it is necessary at all. It feels like we are being told "trust us", but we won't trust you (the voters) by telling you what is happening.
3) Of course, President Zuma can refuse to resign when asked to do so by the NEC or by the "top 6" or by Cyril. Then he can be removed by either a vote of no confidence or impeachment by the National Assembly (If ANC wishes to remove him, of course).
