Polish Prime Minister Donald Tusk and his British counterpart Keir Starmer on Wednesday inked a "major" new defence and security treaty as the embattled UK leader continues to rebuild relations with Europe.
The pair met in London to finalise the agreement, which aims to bolster British borders, tackle organised crime, boost collective defence and further deepen cooperation with the European Union, which the UK voted to leave in 2016 following a divisive referendum campaign.
