Polish poll shows KO lead narrowing as PiS and right‑wing parties gain ground

A United Surveys poll commissioned by VIRTUAL POLAND and conducted between 26‑28 June 2026 with a nationwide sample of 1,000 adults shows the Koalicja Obywatelska (KO) retaining a lead but its margin over Prawo i Sprawiedliwość (PiS) tightening. KO recorded about 29 % support, down slightly from earlier June surveys, while PiS rose to roughly 24 %. The Confederation secured around 10‑13 % and the Confederation of the Polish Crown (Grzegorz Braun’s party) 9‑10 %, with the Left at about 8 %.

Seat simulations based on the poll indicate KO would win 165 seats, far short of the 231 needed for a majority, while PiS would obtain 135 seats and the right‑wing parties would together hold a majority of 248 seats. Smaller parties such as PSL, Razem and Polska 2050 fell below the 5 % threshold. Voter turnout intention stood at 63 %, and undecided voters comprised about 10 % of the sample.
