Warsaw, 14 August 2026

Poland's former prime minister Mateusz Morawiecki has been expelled from the conservative Law and Justice party (PiS) following an internal disciplinary procedure.

The PiS leadership announced the expulsion on Thursday in Warsaw. A party disciplinary court ruled that Morawiecki had violated the party's statutes. The decision came after a long phase of public disputes between the former head of government and the long-standing party chairman Jaroslaw Kaczynski.

Morawiecki had refused to support the legal course set by Kaczynski. Together with other representatives of the economically liberal wing, he founded the internal party group "Development Plus" within the PiS. This platform opposed the dominant national-conservative course of the party leadership.
