Overview
- About 30–40 PiS deputies refused to sign Jarosław Kaczyński’s loyalty declaration, prompting a party council to schedule an expulsion vote for Tuesday, July 28, 2026.
- Mateusz Morawiecki has formed the Rozwój Plus platform and held a founding meeting that positions him to lead a breakaway party if expulsions are confirmed.
- Kaczyński has pushed a harder line by backing figures such as Przemysław Czarnek and pointing to criminal probes of ministers from Morawiecki’s government as justification for ousting dissenters.
- Polls show Rozwój Plus around roughly 7% while PiS has lost several percentage points, a split that could siphon votes to radical groups like Konfederacja and alter who can form a coalition.
- PiS still holds 188 Sejm seats so any formal split would reshape coalition arithmetic for 2027 and could either produce a hard‑right pivot under Kaczyński or a Morawiecki‑led centrist right competing for voters.
