Nationalist Karol Nawrocki sworn in as Polish president

Combative speech in parliament sets Nawrocki on potential collision course with Donald Tusk’s pro-EU coalition

The nationalist historian Karol Nawrocki has been sworn in as the Polish president, using his inaugural address to criticise the EU as he vowed to represent “sovereign” Poland, in a sign of potential clashes to come with the country’s pro-European government.

In a combative speech in parliament aimed squarely at the prime minister, Donald Tusk, and his allies, Nawrocki said on Wednesday that the voters in June’s presidential election had “sent a strong message … that things cannot continue to be governed in this way”.
