The ANC says the DA wants to split the Western Cape from the rest of the country, turning the province into an independent state.
Yesterday the ANC completely sidelined the DA, overlooking any of its members for any of the powerful positions, including committee chairpersons and whips.
Also excluded in the appointments were members of the ANC break-away Cope - despite it being the third largest party in Parliament.
ANC general secretary Gwede Mantashe said the ruling party still needed to develop relations with Cope - referring to the party as "this animal that we do not know yet".
He said the DA's exclusion was because of its "secessionist tendencies in the making and their disrespect for President Jacob Zuma".
Instead the ANC parliamentary caucus voted to reappoint the African People's Convention's only MP, Themba Godi, as head of the powerful standing committee on public accounts (Scopa), even though the APC received only 0,2percent of the vote in the recent general elections.
Mantashe said that the IFP's Ben Skosana would be offered a position as one of the national assembly's three house chairpersons.
The ANC and its alliance partners have lately been accusing the DA of trying to turn the Western Cape into an island, and of pretending that South Africa was a federal state.
"South Africa is not a federal state, there is one South Africa; provinces do not constitute independent states," Mantashe said yesterday.
But DA parliamentary leader Athol Trollip told Sowetan that his party had no intention of seceding the Western Cape from South Africa.
"To punish the DA in Parliament is churlish and unacceptable, showing that the so-called olive branch extended by Zuma is a figment of peoples' imaginations," said Trollip.
Trollip had earlier asked for the DA to chair Scopa or be given a house chairperson position, but Mantashe said the DA had not been given any portfolio committee position because its relationship with the ANC was one of "outright hostility".
