Multi-party system

In political science, a multi-party system is a political system in which more than two meaningfully distinct political parties regularly run for office and win seats in elections. Multi-party systems tend to be more common in countries or jurisdictions that use proportional representation forms of election, compared to those that use winner-take-all elections, a tendency known as Duverger's law.
