The two contenders in Poland's presidential election will fight a close race in this weekend's decisive second round.
Opinion polls show the gap narrowing between the liberal Donald Tusk and conservative Lech Kaczynski.
Polling agencies PBS and OBOP still put Tusk in the lead with around 52%, and Kaczynski credited with around 48%.
But a third agency, PGB, credited Kaczynski with slightly more than 50% of the vote, putting him in front of Tusk for the first time in the campaign, albeit by a margin of less than 1%.
Tusk garnered 36.33% of the vote in the first round two weeks ago, while Kaczynski garnered 33.1% of votes cast.
