The ANC says it has no plans to support calls by opposition parties for a commission of inquiry into the arms deal.
Both the DA and ID tabled motions in Parliament yesterday asking ANC MPs to instruct President Thabo Mbeki to appoint an independent commission of inquiry into the arms deal.
But ANC spokesman Speed Steyn said: "The issue is not on our agenda and I am not sure why the need for it to be on the agenda would arise.
"We have said in the past that those who have evidence of criminal conduct must take that to the relevant authorities."
The UDM's Bantu Holomisa said he was not surprised that the ANC has rejected calls for a commission of inquiry.
"Such an inquiry would put Zuma, Mbeki and everyone else in the ANC on the spot," he said.
Last Friday Pietermaritzburg high court Judge Chris Nicholson threw out charges related to the arms deal of corruption, bribery and money-laundering against ANC president Jacob Zuma.
The judge said "only a commission of inquiry [into the arms deal] can rid our land of this cancer devouring the body politic".
Arms deal opponent Terry Crawford-Browne said the ANC should put pressure on Mbeki to appoint a commission of inquiry.
Opposition parties are set to clash with parliamentary public accounts committee chairman Themba Godi over his lock-down of more than 3000 arms deal documents being kept in Parliament.
