Speaking at a press conference on Thursday, Kaczyński said that once the first association was established, others inevitably followed.
He warned that if the situation worsens, members may face a stark choice: the party's electoral lists or their association – not both.
The comments came after MP Jacek Sasin announced the formation of a new grouping called "Poland First", with former ministers Elżbieta Witek, Tobiasz Bocheński and Patryk Jaki among its leaders.
Sasin insisted the association would operate strictly within PiS and would not build separate structures.
That followed former Prime Minister Mateusz Morawiecki's creation of a rival grouping, "Development Plus", in April.
The move unsettled parts of the party leadership, who saw it as an attempt to build an independent power base.
The tensions point to a broader internal split within PiS between supporters of Morawiecki, known informally as the "scouts" (harcerze), and a rival faction – nicknamed the "butter-makers" (maślarze) – grouped around figures including Sasin, Jaki and Przemysław Czarnek.
According to reports, Kaczyński had already urged the "freezing" of such associations at a party retreat in May, with Morawiecki reportedly insisting his group had no intention of undermining party unity.
Kaczyński said his own focus remained firmly on winning the 2027 parliamentary elections and uniting the right, with the exception of far-right politician Grzegorz Braun's party.
