Karol Nawrocki won Poland’s closely fought presidential election after a final count reversed the picture suggested by the first exit poll. The National Electoral Commission’s complete tally gave the conservative candidate 50.89% of votes, or 10,606,877 ballots, against 49.11%, or 10,237,286, for Warsaw Mayor Rafał Trzaskowski. Turnout reached 71.63%.

The result followed an unusually tense election night. An initial Ipsos exit poll put Trzaskowski ahead by 50.3% to 49.7%, prompting him to claim victory. Later estimates shifted toward Nawrocki, first by 50.7% to 49.3% and then by 51% to 49%, before the official count confirmed the outcome. The June 1, 2025 runoff was among the closest presidential contests in Poland’s post-communist era.

Nawrocki, a historian who has headed Poland’s Institute of National Remembrance, ran formally as an independent with the endorsement of the opposition Law and Justice party, known as PiS. Trzaskowski represented Civic Coalition and was backed by the politically varied governing alliance led by Prime Minister Donald Tusk. The contest therefore carried consequences beyond the presidency itself.

Although Poland’s president has a largely representative role, the office has meaningful authority in foreign and defence policy and can veto legislation. Overriding such a veto requires a three-fifths parliamentary majority, which Tusk’s government does not hold. Nawrocki pledged during the campaign to use that authority against parts of the government’s programme. His victory is likely to constrain proposed changes involving the courts and social policy before the next parliamentary election, scheduled for 2027.

The outcome also extends political alignment between the presidency and PiS after Andrzej Duda completes his second and final term on August 6. Duda had already blocked parts of the coalition’s effort to reverse judicial changes introduced during PiS rule from 2015 to 2023.

Foreign policy was another dividing line. Nawrocki expressed continued opposition to Russia while taking a more critical position toward Ukraine and rejecting Ukrainian membership of NATO. He also received visible support from figures associated with the US conservative movement. Trzaskowski presented himself as a pro-European partner for the Tusk government.

Tusk responded to his ally’s defeat by saying he would seek a parliamentary confidence vote in his coalition. That move underscored the domestic stakes of a presidential result decided by fewer than 370,000 votes. The campaign had required both finalists to pursue voters whose preferred candidates were eliminated in the first round, and late polling placed the difference inside the margin of error. Nawrocki entered office with a fresh national mandate, but the narrow split also revealed an electorate divided almost evenly between competing conservative and pro-European directions. The immediate question was how often the new president would use his veto rather than negotiate with the parliamentary majority.
