In the spotlight: Jacek Kurski

Kurski, formerly a member of right-wing parties such as Christian-National Union (ZChN) and the League of Polish Families (LPR), was elected as a member of Law and Justice (PiS). However, he was removed from the party's ranks following controversial comments about Donald Tusk's grandfather. Kurski claimed that "reliable sources in Pomerania said that Tusk's grandfather volunteered to serve in the Wehrmacht."

However, the Civic Platform's (PO) presidential candidate's grandfathers spent the war in Nazi concentration camps. Kurski tried to explain himself by saying that he got confused and mixed up Tusk's grandfather with Tusk's grandfather's brother, who indeed fought in the German forces.

The controversial remarks might cost Lech Kaczyński a place in the presidential palace. OBOP's latest poll, conducted following Kurski's remarks, showed Tusk is likely to win the second round of the elections by 57 percent to 43 percent, the largest margin so far.

Andrzej Lepper immediately offered Kurski a place in the ranks of Self-defense. Kurski declined and announced that he won't join any other political force.
