The comments made by Keir Starmer, the Prime Minister, on 26 May 2026.
Britain and Poland are already close allies and friends, but the challenges Europe now faces demands an even stronger partnership.
This treaty is the biggest step forward in our defence and security relationship with Poland in a generation, allowing us to confront modern security threats that may be less visible but no less dangerous, and our collective work together will keep our countries safe for years to come.
It also delivers on my commitment to work more closely with European partners to boost security and opportunity for people at home and stability across our continent.
