The Democratic Alliance (DA) Federal Council will meet on Monday at the party headquarters in Bruma, Johannesburg.
Party leaders are set to discuss power-sharing arrangements after the party won about 22 percent of the national vote, a majority in the Western Cape and a presence in every other province.
The DA will also specifically consider the African National Congress' (ANC) proposal to form a Government of National Unity (GNU).
DA national spokesman Solly Malatsi said the party welcomed the possibility of a working relationship with the ANC.
“The DA welcomes that negotiations are moving into a substantive stage. Following the President's announcement last night, our negotiating team will hold further meetings with other political parties to hear their views and reactions. We also expect to receive further information from the ANC on the finer points required for a government of national unity. This will then be considered by the Federal Executive and then Federal Parliament on Monday.”
Opinions about the ANC-DA coalition government are divided
Several stakeholders have expressed mixed reactions to the proposal for the ANC and DA to work together.
Some ANC members taking part in the #NotwithDA campaign in Gauteng have spoken out against a coalition with the DA.
ANC member Esethu Hasane says there has been a proliferation of media articles attempting to put pressure on the ANC by suggesting that the only functioning coalition government is a DA coalition government.
The South African Communist Party was also opposed, with general secretary Solly Mapaila saying a coalition with the DA would go against its anti-capitalist policies.
Meanwhile, the DA set strict conditions for political parties to join the GNU, saying it would only agree to join the ANC's proposed governing structure if Umkhonto we'Sizwe, the Economic Freedom Fighters and the Patriotic Alliance were excluded.
