 The Parliament of Croatia ( Croatian : Sabor ) is a unicameral legislative body . A second chamber , the Chamber of Counties ( Croatian : <unk> <unk> ) , was set up in 1993 pursuant to the 1990 Constitution . The Chamber of Counties was originally composed of three deputies from each of the twenty counties and the city of Zagreb .

The number of Sabor representatives can vary from 100 to 160 ; they are all elected by popular vote and serve four @-@ year terms . 140 members are elected in multi @-@ seat constituencies , up to six members are chosen by proportional representation to represent <unk> living abroad and five members represent ethnic and national communities or minorities . The two largest political parties in Croatia are the SDP and the Croatian Democratic Union ( HDZ ) . The last parliamentary election was held on 4 December 2011 in Croatia and on 3 and 4 December 2011 abroad .
