This comes after the ANC announced on Wednesday that a number of former ministers aligned to former president Jacob Zuma were to head critical committees.
ANC secretary-general Ace Magashule, however, defended the decision to appoint people who have been implicated in state capture, saying they had not been found guilty of any crime in a court of law.
In announcing the list, Magashule said former mineral resources minister Mosebenzi Zwane would chair the transport committee, while Faith Muthambi would chair the co-operative governance committee, and Bongani Bongo was to head the home affairs committee.
Cosatu said: “The federation is not pleased that some of the chairpersons’ names have been raised at the various commissions of inquiry into state capture, etc. The ANC needs to ensure all its public representatives reflect the highest levels of integrity at all times, and that there are actually real consequences for those who misbehave. The patience of voters is not limitless.”
