The Polish parliament will hold a vote of confidence next Wednesday after an opposition-backed nationalist candidate defied polls to narrowly win the presidency.

Prime Minister Donald Tusk first announced the vote on Monday after his coalition’s candidate, Warsaw Mayor Rafał Trzaskowski, was defeated by Karol Nawrocki, who is pro-Trump and was supported by the conservative-nationalist Law and Justice Party (PiS).

The ballot will take place on June 11, the Polish parliament’s speaker Szymon Hołownia said Tuesday, according to Poland’s national news agency.

Nawrocki’s victory jeopardizes the center-right Tusk government’s ability to enact its agenda, as the president has veto power over legislation. The outgoing president, Andrzej Duda, also hails from PiS and has been a thorn in Tusk’s side.

But Tusk has insisted Nawrocki’s win will “change nothing,” framing the vote of confidence as a projection of his government’s strength.

“I want everyone to see, including our opponents at home and abroad, that we are ready for this situation, that we understand the gravity of the moment, but that we do not intend to take a single step back,” Tusk said.

With 242 MPs in the 460-seat lower house, Tusk’s coalition government — which came to power toward the end of 2023, ending almost a decade of PiS rule — is likely to survive the June 11 vote.
