The ANC was blocking all attempts to fight corruption, DA Parliamentary leader Lindiwe Mazibuko said on Saturday.
"The DA tried to pass two bills in Parliament to fight the scourge of corruption, but ANC blocked them," Mazibuko said in a speech prepared for delivery at a skills development workshop in Klipfontein.
One bill would have prevented civil servants from doing business with government, the other would have stopped companies in which political office bearers had a stake, from doing business with the state, she said.
She said the African National Congress said the bills, if passed into law, would hurt business.
Mazibuko told her audience that the ANC had left the poverty-stricken all alone.
"You were left alone when what you needed was a partner, someone to give you a hand onto the ladder of prosperity."
Billions of rands that could be used on skills training, the provision of basic services and help entrepreneurs were being stolen by a corrupt few, said Mazibuko.
