Timo Soini: "We are not extremists, so you can sleep safely"
A nationalist party has taken nearly a fifth of votes in Finland's general election, the electoral commission says.
The True Finns finished just behind the conservative NCP and the Social Democrats on around 19%.
While the Social Democrats have called for changes on EU bail-outs, including the planned Portuguese rescue, True Finns opposes the plans altogether.
A hostile Finnish government could theoretically veto the package.
Unlike other eurozone countries, Finland's parliament can vote on whether to approve the measures.
Correspondents say the increased sway of Euro-sceptics in Finland's parliament could hold up any further bail-out deals.
As the biggest party, the NCP is tipped to lead the next government with former Finance Minister Jyrki Katainen likely to become prime minister of whatever coalition emerges, replacing Mari Kiviniemi of the Centre Party.
