ANC chief whip Jackson Mthembu says a judicial commission of inquiry into state capture must be instituted as a matter of urgency.
Mthembu was speaking to media on the sidelines of the ANC national conference in Johannesburg on Monday.
"On state capture we must institute as a matter of urgency, in fact the courts have said so, a judicial commission of inquiry. Case closed," he said.
Mthembu has come out as a staunch backer of Deputy President Cyril Ramaphosa for the ANC top spot, and has spoken out on state capture and corruption in government.
"How do you get to the bottom of this/ when you don't have an independent and credible body to get deeper into this?" he asked.
"This is what the former public protector (Thuli Madonsela) said... come with a judicial commission of inquiry, investigate this matter, but there is a prima facie case... whoever is found [guilty] must then face the consequences."
