Finland's electoral commission says the conservative National Coalition Party has won the Nordic country's election, while the True Finns, a nationalist party opposed to eurozone bailouts, made the strongest gains.
With all votes counted, the conservatives won 20 percent for 44 seats in the 200-member Parliament. The opposition Social Democrats got 42 seats and the nationalist True Finns soared from six to 39 seats.
The True Finns oppose bailouts for cash-strapped European countries, while the Social Democrats have called for changes to how they are funded.
The outcome means conservative leader Jyrki Katainen will have to invite at least one of them to coalition talks, raising questions about Finland's support for rescue packages that need unanimous approval in the 17-member eurozone.
Finland's parliament, unlike others in the euro zone, has the right to vote on EU requests for bailout funds, meaning it could hold up costly plans to shore up Portugal and bring stability to debt markets.
Timo Soini, the True Finns leader, said the party would at least "get an invitation to talks" on a new government, which is expected to be formed in mid- to late-May.
The winning parties will need to form a coalition to get a majority in the 200-seat parliament and analysts expected the talks to be difficult. Nevertheless, Finland's policy direction was expected to undergo changes.
National Coalition minister Jan Vapaavuori on Friday played down fears of an anti-euro government. The True Finns, he said, would probably be asked to tone down their rhetoric as a condition of joining the coalition.
The Social Democrats, who are critical of the bailout but supportive of the EU, would be easier to get on board, he said.
Mr. Soini, however, warned on Sunday that the EU bailout plan for Portugal will not survive,.
"The package that is there - I do not believe it will remain," he said on Finnish national broadcaster YLE.
