The Croatian Parliament or the Sabor is the unicameral representative body of the citizens of the Republic of Croatia; it is Croatia's legislature. Under the terms of the Croatian Constitution, the Sabor represents the people and is vested with legislative power. The Sabor is composed of 151 members elected to a four-year term on the basis of direct, universal and equal suffrage by secret ballot. Seats are allocated according to the Croatian Parliament electoral districts: 140 members of the parliament are elected in multi-seat constituencies, 8 from the minorities and 3 from the Croatian diaspora. The Sabor is presided over by a Speaker, who is assisted by at least one deputy speaker (usually four or five deputies).
