In a memo to political parties, parliament said the number of ANC MPs who took part in the vote had been under-reported by three MPs, which means 171 voted in favour of the motion instead of the 168 captured on Tuesday.
The list also shows that despite his earlier protest, MKMVA president Kebby Maphatsoe, who is aligned to the RET faction, voted in support of the motion.
Maphatsoe on Friday conceded he had no choice but to do so following instructions from ANC national chairperson Gwede Mantashe, who told party MPs no dissent would be allowed during the vote.
