The resignation of three prominent ANC Members of Parliament (MPs) this week could possibly see others among the ruling party's caucus give up their seats.
Former Energy Minister Tina Joemat-Pettersson has resigned as an MP following the resignations of former ministers Mcebisi Jonas and Dipuo Peters.
EWN's Parliamentary correspondent Gaye Davis says it's entirely possible that other ANC MPs could make an exit.
Davis reports that axed Tourism Minister Derek Hanekom has said he will continue on the back benches as an MP and see his term to an end.
She explains that the resignation of other ANC MPs may hinge on the outcome of the no confidence debate set for Tuesday 18 April at 2pm.
Quite a lot will depend on how Derek Hanekom votes that day. He might find himself in trouble with his party if he decides to break ranks and votes in favour of that motion.— Gaye Davis, Parliamentary correspondent for EWN
At the same time, the former Minister of Public Service and Administration Ngoako Ramatlhodi says he has not yet decided whether he will stay on as an ANC MP.
