Cain's motion to adjourn the parliament for over a week was defeated by the Country Party and the UAP, and Opposition Leader, Albert Dunstan, moved that Parliament resume the next day, giving notice that he would move a motion of no confidence against Cain's government, confident it would be carried by the CP–UAP alliance.
