The Parti Islam SeMalaysia (PAS)'s shura council secretary Nik Zawawi Salleh said the decision was made as the party was disappointed with the DAP's fervent "provocation" against it.
He said DAP's action was a breach of the opposition alliance cooperation spirit.
The DAP had constantly interfered in PAS' struggles, policies and objectives, he said adding the PAS would maintain its ties with the other opposition party the Parti Keadilan Rakyat (PKR).
Zawawi added that this decision would then be handed to PAS' central committee to be executed.
PKR had also appeared to agree with DAP, with its president Wan Azizah Wan Ismail saying that the opposition alliance no longer functioned normally as a coalition.
