WARSAW, May 27 (Reuters) – Poland wants the closest possible diplomatic relations with the United Kingdom, focusing on defence against Russia, ​Polish Prime Minister Donald Tusk said ‌on Wednesday before leaving for London.

Britain will sign a new defence and security treaty with Poland on Wednesday to strengthen defence cooperation in the face of ‌increasing ​hostile threats across Europe, the ⁠government said, following similar ⁠deals with France and Germany.

While Britain and Poland are already close allies, British Prime Minister Keir Starmer said in a statement ​on Tuesday that “the challenges Europe now faces demands an even stronger partnership”.

The continent has ⁠been under pressure from U.S. ⁠President Donald Trump’s administration to ​take greater responsibility for its own defence. Both ​countries are also key allies of Ukraine in ‌its war with Russia.

“Both sides emphasize that Russia is a strategic threat, also a long-term one, for Poland, for Great Britain, for ⁠NATO, and therefore our cooperation should be focused on securing Poland and other countries against the Russian ⁠threat,” Tusk ‌told reporters on Wednesday.

Tusk had ⁠earlier said that beyond defence, a ​significant ‌part of the treaty focuses on ​cybersecurity. Poland ⁠says its role as a hub for military aid to Ukraine has made it a key target for Russian espionage, cyberattacks and disinformation.
