National Coalition Party candidate Alexander Stubb leads Yle's final poll before presidential election day on Sunday. His support has fallen since December's poll, however.
The latest poll, conducted by Taloustutkimus, suggests that Stubb would have the support of some 27 percent of voters, compared to 31 percent in December.
In second spot was Pekka Haavisto (Green), who is running as an independent candidate backed by a voters' association and the Green party.
Finns Party candidate Jussi Halla-aho has shown the greatest increase in support, rising from 10 percent in December to 18 percent now.
Halla-aho has overtaken Olli Rehn, who is backed by a voters' association and the Centre Party. Rehn's support also rose, from 12 percent in December to 14 percent now.
The poll was conducted via phone interviews. Taloustutkimus Managing Director Jari Pajunen said that phone interviews have proven more accurate than online surveys, which have been used in other recent presidential polls.
The poll was conducted between 17 and 23 January.
In second-round matchups, Stubb appears to be the overwhelming favourite. According to the poll, he would beat every possible second-round opponent.
The poll suggests that Haavisto's chances depend on his second-round opponent. He would struggle if he faces Stubb, and the race could be very even in the unlikely event of a second-round matchup with Rehn. Against Halla-aho, Haavisto would be the favourite.
Pajunen said, however, that the number of undecided voters had grown and now stands at some 15 percent.
The likely second-round election would take place on Sunday, 11 February, with advance voting from 31 January to 6 February.
