Polish Prime Minister Donald Tusk said Monday that he would ask parliament to hold a vote of confidence in his coalition government after his ally lost a presidential runoff.

The result of the weekend election leaves Tusk politically weakened, and there are questions about whether his multiparty coalition can survive to the end of its term in late 2027.

It wasn’t immediately clear when the confidence vote might take place.

Tusk's announcement came in a recorded announcement posted to social media after a vote count confirmed that that conservative Karol Nawrocki won Poland’s weekend presidential runoff election, according to the final vote count on Monday.

Nawrocki won 50.89% of votes in a very tight race against liberal Warsaw Mayor Rafał Trzaskowski, who received 49.11%.

Tusk said he is prepared to work with Nawrocki if he “shows a willingness to cooperate.”

Tusk's government exists separately from the presidency but the president holds power to veto laws, and Nawrocki's win will make it extremely difficult for Tusk to press his pro-European agenda.

If Tusk survives the confidence vote, it would show he still has a mandate to govern.
