A formateur is a politician who is appointed to lead the formation of a coalition government, after either a general election or the collapse of a previous government. The role of the formateur is especially important in the politics of Belgium, the Netherlands, Luxembourg, Italy, Israel, Czech Republic, and Spain. These countries have a parliamentary system, where the executive derives its mandate from majority support in the legislature. They also use proportional representation for elections to parliament, and have a multiparty system that makes it improbable for one party to win an outright majority. There may be several combinations of parties which might form a coalition. The formateur is traditionally appointed by the head of state but in the Netherlands that became the right of the Speaker of the House of Representatives in the early 21st century.
