Law and Justice's leader Jaroslaw Kaczynski got 46.99 percent of votes, PKW reported. The turnout reached 55.31 percent.

In the June 20 first-round presidential election, Komorowski received 41.54 percent of votes, while Jaroslaw Kaczynski received 36.46 percent, according to the PKW. Turnout reached 54.94 percent.

According to election law, since no one secured an outright victory by garnering over 50 percent of the vote, a runoff between the two top contenders must be held in two weeks. A simple majority is needed to win the vote.

Komorowski took over presidential duties after the death of President Lech Kaczynski in an air crash on April 10 near Smolensk, Russia.

The presidential elections were originally scheduled to be held in October. Komorowski decided to call for an early election in accordance with election law.
