Former Polish Prime Minister Mateusz Morawiecki has stepped down as head of the European Conservatives and Reformists (ECR) group in the European Parliament. This decision follows his recent expulsion from Poland's ruling Law and Justice (PiS) party. The resignation was announced on social media by Piotr Müller, a former spokesperson for Morawiecki. The move is directly linked to a growing political rift within the PiS party itself. Morawiecki's departure signifies increasing internal divisions and instability within the Polish opposition. The Polish Press Agency (PAP) reported that the resignation is a consequence of the ongoing party conflict. This development could reshape the political landscape both in Poland and within the ECR group.
