PiS leader Jarosław Kaczyński and Marek Woch, head of the Non-Partisan Local Government Activists group, announced the initiative on Wednesday.
The agreement is intended as a first step toward broader cooperation among Poland’s divided conservative and nationalist parties. Its final form has yet to be decided.
Kaczyński said the groups could form a direct alliance or establish a special civic election committee. He said PiS currently preferred the second option.
'We must unite'
"We must unite so that the Senate ceases to be a place dominated by the left and left-wing liberals," Kaczyński said.
Polish senators are elected in single-member districts, where the candidate receiving the most votes wins. This gives parties a strong incentive to agree on one candidate in each district rather than divide their supporters among several contenders.
The parties that now form Prime Minister Donald Tusk’s governing coalition used such an arrangement in the 2023 election. Their candidates won 66 Senate seats, while PiS secured 34.
Woch thanked Kaczyński for his willingness to work on a similar pact for right-wing groups. He said the 2023 result demonstrated the need for cooperation among parties that might otherwise compete for the same voters.
His movement, rooted in regional and municipal politics, failed to enter parliament in 2023.
Woch said it was prepared to contest the next election to the Sejm, the Polish parliament’s more powerful lower house, independently.
Woch has promoted a right-wing Senate pact since October, when he appeared with Grzegorz Braun, leader of the far-right Confederation of the Polish Crown group.
Kaczyński has repeatedly called for the unification of Poland’s right-wing parties. He has said this should include PiS, Braun's party and the two main groups within Confederation, the National Movement led by Krzysztof Bosak and New Hope led by Sławomir Mentzen.
Relations between PiS and Confederation remain strained. Politicians from the two parties have traded criticism, while Confederation figures have previously dismissed PiS overtures as attempts to win over their voters.
Politicians from both groups said in late 2025 that President Karol Nawrocki could serve as a patron of a broader Senate agreement. No deal involving the major Confederation groups has been announced.
