Morawiecki forms Rozwój Plus caucus but stays in PiS — checkmate for Kaczyński?

Mateusz Morawiecki and his allies are forming their own parliamentary caucus called Rozwój Plus while remaining formally within PiS. The move is seen as a calculated response to Jarosław Kaczyński's use of the party's disciplinary tribunal. By staying inside PiS while building a separate group, Morawiecki places Kaczyński in a politically difficult position.
