Political parties in Greece play a crucial role in the country's democratic system. The main parties include the New Democracy party, which is center-right, and the Syriza party, which is left-wing. Other notable parties are the Movement for Change and the Communist Party of Greece. Elections in Greece are held every four years, and the political landscape is characterized by a multi-party system. Coalition governments are common, as no single party often secures an outright majority. This dynamic reflects the diverse political opinions and interests of the Greek population.
