The matter of embattled Home Affairs Minister Malusi Gigaba didn't arise when President Cyril Ramaphosa addressed the ANC caucus on Tuesday morning.Unity was the main topic of discussion, ANC secretary general Ace Magashule and chief whip Jackson Mthembu told the media after the special caucus meeting, which was addressed by Ramaphosa in his capacity as president of the ANC.It has been a week the minister would rather forget: a sex video emerged, the Constitutional Court didn't grant him leave to appeal a court ruling that he lied, and the Public Protector found that he not only violated the executive ethics code, but also the Constitution, by "deliberately telling untruths under oath".READ: 'There will be hell to pay' if I am removed from ANC - GigabaOn Monday, a draft report of the Portfolio Committee on Public Enterprises' inquiry into Eskom also leaked, in which Gigaba was named as one of those who should be criminally investigated.Gigaba claimed there was a "devious plot" against him, adding that the committee had been part of a "well-orchestrated political campaign"."There was no discussion on comrade Gigaba in caucus," Mthembu said, responding to journalists."The committees of Parliament [are] not part of any plot."Gigaba cuts a lone figureHe said Parliament would continue to work "without any fear or favour".
