(CNN) Finland's parliamentary election results show the Social Democratic Party (SDP) winning with 17.7% of the votes, according to CNN's local affiliate Italehti.

The tight race saw the anti-immigration right-wing Finns Party come in second place with 17.5%, while their coalition partners the National Coalition Party, and the Center Party scored 17% and 13.8% respectively, Italehti reported.

According to Reuters , this is the first time in a century that no party has won more than 20% in an election, and coalition talks are likely to be protracted.

All centre-left and left-wing parties saw an increase in their vote, with the Green League coming in fifth with 11.5% of the vote, followed by the Left Alliance at 8.2%.

Between them, the three left-leaning parties should return 76 lawmakers, according to Italehti's estimates, short of a majority in Finland's 200-seat parliament, meaning a governing coalition will likely have to include one of the main centrist parties.
