Karol Nawrocki was sworn in as Poland’s new president on Wednesday after winning a narrow election in June.
The former historian, who had no political experience before the campaign, secured victory with support from conservative circles, including US President Donald Trump.
Though Poland’s prime minister manages most of the daily government work, the president holds key powers, such as approving or blocking laws and guiding foreign policy.
In his first speech as president, Nawrocki said he wants Poland to stay within the European Union, but without giving up control over national decisions.
He opposed joining the euro and said he would not support any shift of power from Warsaw to Brussels.
He also spoke against illegal immigration and called for a new Polish constitution to be ready by 2030.
Nawrocki’s win was a setback for current Prime Minister Donald Tusk, who previously served as European Council president.
Tensions between the president and prime minister may rise, especially with parliamentary elections set for 2027.
At 42, Nawrocki entered politics for the first time during this campaign. He was backed by the right-wing Law and Justice party but ran as a non-partisan candidate.
Supporters view him as a defender of traditional values, while critics point to past controversies during his campaign.
These included claims related to property taxes and alleged involvement in arranging escorts, which he denied.
His campaign gained momentum after meeting Donald Trump at the White House. Conservative groups from the US also voiced support for his candidacy.
His slogan, “Poland first, Poles first,” echoed nationalist themes, and he often described the EU as a threat to national control.
Nawrocki has also spoken out against providing more support to Ukraine or supporting its efforts to join NATO or the EU, raising concerns among neighboring countries and allies.
