Voters in Iceland appear to have rejected incumbent parties in a parliamentary election. Partial results show a center-left party in first place in the North Atlantic island nation.

Iceland's centre-left Social Democratic Alliance became the biggest party in a snap election that unseated the ruling coalition of the past seven years, the final count showed on Sunday. The Social Democrats gained 15 seats in the 63-seat parliament with 20.

Iceland's opposition Social Democrats ousted Prime Minister Bjarni Benediktsson's ruling Independence Party in a snap election triggered by the collapse of his coalition.
