Poland's PiS Party Splits After Loyalty Pledge Ultimatum 2026

The PiS party split in Poland has reshaped the country's political landscape as former Prime Minister Mateusz Morawiecki and his allies were forced out over factional disagreements. The loyalty pledge ultimatum issued by party leader Jarosław Kaczyński effectively expelled dozens of MPs who refused to sign, marking a dramatic fracture in Poland's main rightwing opposition.

Background of the PiS Party Split

The Law and Justice (PiS) party has been one of Poland's most successful political forces since 1989, ruling for 10 years across two stints and winning four out of eight presidential elections. However, after losing the 2023 parliamentary election to a pro-European coalition led by Donald Tusk, PiS remained the largest single party in parliament until this split.

Kaczyński’s loyalty oath required all MPs to pledge unwavering allegiance to the party line. Those who refused were deemed to have resigned. The rebel MPs insist they never intended to leave but may be formally expelled at a leadership meeting on Tuesday. “Everyone knew what they were signing, and at the same time everyone knew what the consequences of not signing would be,” Kaczyński stated.

Why Did the Loyalty Pledge Trigger a Split?

Months of bitter disagreements over policy direction preceded the ultimatum. PiS struggled to respond to the rising libertarian-right Confederation and the far-right Confederation of the Polish Crown, splitting the conservative vote into three. Morawiecki, who served as prime minister from 2017 to 2023, set up a growth-oriented policy group in April to broaden the party’s electoral appeal on the centre-right.

Implications for Poland's 2025 Election

The PiS party split could cost it the status of largest parliamentary party. With the election expected in 2025, the fractured right wing may struggle to mount a unified challenge against Tusk’s coalition. The split also opens space for Confederation and other right-wing groups to gain ground.

Political analysts warn that the division may permanently weaken the conservative bloc in Poland, mirroring trends seen in other European democracies where populist parties fragment under internal pressure.
