Polokwane - SACP general secretary Blade Nzimande on Thursday lambasted opposition parties during his speech at Cosatu's May Day rally in Polokwane.
"In the DA black people are only good enough to go march on the street but not good enough to go to Parliament," he told thousands of people at the Peter Mokaba Stadium.
"On the 7 May [elections] let us teach the opposition a lesson."
Referring to Julius Malema's Economic Freedom Fighters, he called on people to vote for the African National Congress and teach a lesson to the "tenderpreneurs who have stolen our colours".
A tenderpreneur is a politician who seeks self-enrichment by trying to get government contracts.
"Let our youth not be fooled... Only the ANC will empower our youth."
Nzimande called on the working class to close ranks around the ANC.
"The working class must be present."
Earlier, Nzimande arrived at the stadium with President Jacob Zuma and Congress of SA Trade Unions' president Sidumo Dlamini.
The crowd cheered for the leaders and chanted Zuma's name.
