Seat arithmetic

Prof. Jarosław Flis of the Jagiellonian University converted the results into seats in the basic variant. KO would receive 188 seats, PiS 96, Konfederacja 72, Konfederacja Korony Polskiej 53, Nowa Lewica 31 and Rozwój Plus 20.

Context: the Tribunal dispute

The poll follows an escalation around the Constitutional Tribunal on the night of 30 to 31 October, when police were mobilised and a crowd gathered in front of the court. Rzeczpospolita reports that the president returned from Senegal and intervened at the Tribunal that night. Prime Minister Donald Tusk said the Tribunal had already begun normal work. The same paper reports that police action at Aleja Szucha drew attention during these events.

De-escalation and the undecided vote

According to Rzeczpospolita, Tusk has offered a meeting to President Karol Nawrocki, and Władysław Kosiniak-Kamysz has proposed a reset in relations. The paper argues that the voters KO lost went to the undecided group rather than to opposition parties, which leaves room for the ruling side to win them back. The IBRiS figures show that the undecided share, not the opposition, gained the most in this round.
