Finns are voting in parliamentary elections that will determine which coalition of parties can lead the country out of a three-year recession.

Conservative Prime Minister Alexander Stubb acknowledges economic reforms should have been made earlier by the government during its four-year term. Campaigning for Sunday's election was dominated by arguments over unemployment, benefit cuts and the rising national debt.

Recent opinion polls give the lead to the opposition Center Party led by Juha Sipila, a self-effacing millionaire businessman who turned to politics only four years ago.

The two main government partners, Stubb's conservative Nation Coalition Party and the Social Democrats, are both vying for second place alongside the populist Finns Party, which opposes European bailouts and immigration.
