Minister in the Presidency Jeff Radebe on Friday praised government’s work in fighting corruption, saying it was walking the talk.

Over the past three years, the Special Investigating Unit (SIU) had recovered cash or assets to the value of R204-million, and managed to have contracts to the value of R755-million invalidated and set aside, he said at an International Anti-Corruption day event at Unisa in Pretoria.

"That is walking the talk," said Radebe.

Radebe said President Jacob Zuma, who was spearheading the fight against corruption, had signed 27 proclamation orders since April 2013. These empowered the SIU to investigate serious cases of malpractice, maladministration, and corruption.

"More than three years ago we committed ourselves to ensure the conviction of about 100 persons who are involved in corruption, where the total amount is about R5-billion."

Radebe said government had secured the conviction of about 32 people in corruption cases involving a total of R3-billion. Another 58 people had been convicted of fraud involving a total of R188-million.

He urged South Africans to help fight corruption, which he said required an active citizenry.
