Voting has concluded in Finland’s parliamentary election with advance results on Sunday showing the Social Democrats slightly ahead.

With just over 35% of ballots counted, the party is leading with 18.9% of the vote, ministry of justice data shows.

Should they win, the country will have its first left-wing leader in 20 years.

The centre-right National Coalition is second, while ex-PM Juha Sipila’s Centre Party is third. The right-wing anti-immigration Finns Party is fourth.

These early figures are largely based on votes cast in advance. The final results will be announced in the coming days.

Finnish state broadcaster YLE tweeted the advance tallies, showing how close the top four parties sit with their share of the vote.
