A number of papers on Wednesday quoted a poll as indicating that 22.4 per cent of the public would vote for the True Finns party if a general election were held at the time of asking.
The True Finns party overtook the National Coalition party, with 20.6 per cent of the respondents saying they would vote for the latter.
The Social Democrats came in third with 18.6 per cent and the Centre party fourth with 14.4 per cent.
Commissioned by Etelä-Suomen Sanomat, Kaleva, Turun Sanomat and Väli-Suomen sanomalehdet, a syndicate, market research company Taloustutkimus interviewed some 1,400 people.
The survey was carried out late last week after the True Finns party announced it would remain in opposition. The announcement came after the National Coalition party and the Social Democrats struck a deal to approve eurozone bailouts with some conditions attached.
In last month's general election, the National Coalition party won 20.4 per cent of the vote, followed by the Social Democrats (19.1 per cent), the True Finns party (19.1 per cent) and the Centre party (15.8 per cent).
