Parliamentary Elections
How elections work in parliamentary systems, where voters choose legislators who then choose the executive.
Voting for a Legislature, Getting a Government
In parliamentary systems, voters elect members of parliament, and the government (the prime minister and cabinet) is formed by whichever party or coalition commands a majority in the legislature. This means voters do not directly choose the executive. The prime minister serves only as long as they maintain the confidence of parliament, and an election can be called (in most systems) if the government loses a confidence vote.
This creates a fundamentally different dynamic than presidential elections. In a presidential system, the executive has a fixed term regardless of legislative support. In a parliamentary system, the executive and legislature are fused. A government that loses its majority falls, either triggering a new election or the formation of a new coalition. This makes coalition arithmetic the central drama of parliamentary elections: it matters not just how many seats each party wins, but which combinations of parties can form a majority.
