WARSAW, Dec 13 (Reuters) - New Prime Minister Donald Tusk’s government was sworn in by Poland’s president on Wednesday, the final step in a transfer of power that marks a huge change after eight years of nationalist rule.

Following years of disputes between Warsaw and Brussels under the previous government, led by the Law and Justice (PiS) party, Tusk’s appointment has raised hopes of smoother relations with the rest of the European Union.

“Faithfulness to the provisions of the constitution will be the trademark of our government,” Tusk said, adding that he thought voters’ desire to see the rule of law re-established was behind record turnout in an Oct. 15 election.

Last-minute spending by the previous government has also added to strains on the budget, complicating Tusk’s efforts to deliver on campaign pledges.

With concerns growing in Kyiv about its Western allies’ commitment to funding its defence against Russia’s invasion, Tusk said on Tuesday that Poland would advocate for continued support.

Ukraine faces the possibility that Hungary will not give the green light for it to start EU accession talks at a Brussels summit.
