## Summary

Mateusz Morawiecki, who led [Poland](/en/entity/poland) as prime minister from 2017 to 2023, confirmed on August 4 that his breakaway parliamentary faction will formally constitute itself as a new party by October 2026. PiS leader Jarosław Kaczyński, whose party Morawiecki previously served as premier, responded by ordering members to sign a loyalty pledge rejecting external associations and demanding the group dissolve. Morawiecki ruled out any future cooperation with current Prime Minister [Donald Tusk](/en/entity/person/donald-tusk), describing opposition to Tusk as the new party's central organising principle.

## Why it matters

The split fractures Poland's main right-wing opposition bloc at a time when Tusk's governing coalition already faces internal tensions. A formal new party led by Morawiecki would compete with PiS for the same voter pool, potentially fragmenting the opposition's capacity to mount a unified challenge ahead of the next Sejm elections. Kaczyński's loyalty-pledge response signals PiS intends to treat the breakaway as a hostile act rather than a negotiable internal dispute.

## What to watch

- Whether PiS expels Morawiecki's group from the party, completing the split
- The new party's October launch and its initial membership and platform
- Whether Morawiecki's faction can attract additional PiS defectors or coalition with smaller right-wing parties
