The main competitors at the Polish presidential runoff, the twin brother of the late Polish president and the interim head of state, took part in the elections on Sunday.
The first round of early elections, forced by President Lech Kaczynski's death in the April air crash in western Russia, was held on June 20. It was narrowly won by acting president Bronislaw Komorowski (41.54%), a pro-EU, moderate member of the governing Civic Platform party.
His main opponent Jaroslaw Kaczynski, an ex-prime minister who now leads the conservative Law and Justice party, was second with 36.46% of the vote.
The turnout forecast for the runoff is about 54%.
Kaczynski came to the polling station with his niece, Marta Kaczynski (daughter of the late Polish president and his wife) and her family.
"These polls are very important for Polish democracy," Kaczynski said after the voting, adding he was going to visit his mother Jadwiga Kaczynski, who was still undergoing treatment in hospital since her health had worsened considerably after she had been told of her son's death.
"I will go to see my Mom. Then, I guess, I deserve a brief rest so I will have to finally sleep a bit," Kaczynski said.
Bronislaw Komorowski was accompanied at the polling station by his wife, Anna.
Responding the journalists' questions about the candidate, Komorowski voted for, he said he had given his vote "for the best of the candidates".
Preliminary voting results and exit polls are set to be announced at 22:00 Moscow time (18:00 GMT), soon after the last polling stations close.
Polish Central Election Committee is set to sum the results of the election on Monday, July 5.
