Stilly, to refine Charmion's point, in this 44th Parliament, the two more "progressive" parties have entered into a "supply and confidence agreement" to manage the risk that the government might fall at a less than propitious moment, i.e. one that neither party chose and that gives an advantage to the Conservative opposition. "Supply" refers to the government's taxing and spending plan and involves three votes understood to be confidence motion in each year in Parliament.
