The South African Communist Party (SACP) says that President Jacob Zuma's involvement in the judicial commission of inquiry into state capture will compromise the process.
The SACP has called for an independent judicial commission of inquiry into state capture to be established.
This comes after the ANC agreed to support the establishment an inquiry into wider state capture going as far back as 1994.
SACP spokesperson Alex Mashilo says the movement and battle against state capture cannot be left only to the tripartite alliance or bureaucratic institutions.
Mashilo says the SACP is building a broad political front to build momentum and will not simply walk away from the ANC.
Mashilo warned about politically compromised individual's being involved in the inquiry and added that the courts alone cannot protect state institutions.
At the same time, Corruption Watch head David Lewis says the broad inquiry led by Zuma will unlikely be binding or of any substance.
I don't feel confident that it will reach direct, sharp conclusions.. or that its recommendations will be acted on if they are.— David Lewis, Executive Director of Corruption Watch
He says the police and the National Prosecuting Authorities NPA should be the one's leading the focused investigation into state capture.
Lewis adds the appointment process surrounding the Police Minister, head of Hawks and head of National Prosecuting Authorities (NPA) needs to be reviewed.
Mashilo also spoke at length about the SACP's bid to put political pressure on police, state capture, their July congress and decisions to choose deputy president Cryil Ramaphosa to speak at the event.
