Bulgaria elects a head of state—the president—and a legislature on a national level. The president is elected for a five-year term by the people directly. The National Assembly (Narodno Sabranie) has 240 members elected for a four-year term by proportional representation in multi-seat constituencies with a 4% threshold. Bulgaria has a multi-party system in which usually no party receives a required majority and parties have to collaborate to form governments, generally via confidence and supply or coalition agreements.
