The Latest: Populist party amazed by Finland election result
The Latest on Finland's parliamentary election (all times local):
The chairman of the populist Finns Party says he was truly surprised at how his party performed in Finland's parliamentary election.
A complete count of votes from Sunday's election had the euroskeptic party winning 39 seats in the 200-seat Finnish legislature, one fewer than the center-left Social Democratic Party that received the most votes.
Finns Party chairman Jussi Halla-aho also received the most votes by far of any candidate who ran for the Eduskunta legislature. Finnish media are suggesting that could put him in the role of kingmaker in the next government.
An elated Halla-aho called it a "day of joy" and said: "I certainly could never have expected a result like this. Honestly speaking, none of us expected this kind of result."
The leader of Finland's center-left Social Democratic Party vowed to focus on climate and social policies after election results indicated his party won the most seats in parliament.
Antti Rinne, a former union leader and former finance minister, celebrated with supporters at an election party in central Helsinki.
He called on them to "take the Finnish society toward a sustainable climate, social and economic policies."
With 99 percent of the votes counted, the Social Democrats appeared to have won 40 seats, just edging out the populist euroskeptic Finns party, which got 39.
Rinne also told them: "I have to make a honest confession: I hoped still for a better result."
Election returns in Finland indicate the Social Democratic Party was the top vote-getter in the country's parliamentary election, trailed closely by the populist euroskeptic Finns Party.

National Coalition Party leader Petteri Orpo predicted that postelection talks on forming the next Finnish government will be difficult because "whoever comes out first will face hard time in working out a government program."

Social Democratic leader Antti Rinne told reporters after voting Sunday in a municipality north of Finland's capital of Helsinki: "I have not closed out the Finns Party. I have said that if we're the first party, we are going to ask all parties the same questions."
Rinne said his values "differ very much" from those of the chairman of the euroskeptic, anti-immigrant Finns, Jussi Halla-aho.
He said" 'That's a big question for me. We need to have a government where there is the same value base."
Polls before the parliamentary election predicted the Social Democrats would place first with voter support of 19%-21%. The polls had the Finns Party coming in second or third with 15%-16% of the vote.
While the debate over climate change has dominated the campaign for Finland's parliamentary election, the populist Finns Party disagrees with other main parties on what measures to take.
Finns Party leader Jussi Halla-aho told reporters at a Helsinki polling station Sunday that "we want a more moderate and sensible climate policy that does not chase industries away from Finland to countries like China."
The Finns Party, which ahead of Sunday's vote has been polling in second place behind the opposition Social Democrats, has been gaining momentum among rural voters and others who find the climate change proposals of other political parties too daunting.
Some of those proposals include boosting the number of electric vehicles, cutting meat consumption through taxes and switching to more vegetarian food in public places like schools.
Greenpeace is calling the parliamentary vote in Finland the "climate election," saying that "never before has climate and the limits of planet Earth been discussed with such seriousness in Finland."
