Keir Starmer meets Poland’s Prime Minister Donald Tusk to formalise a defence and security agreement. Multiple reports say the pact is intended to strengthen collective defences and improve cooperation on security issues affecting the UK and Europe. The agreement is described as aiming to protect British borders, including through measures designed to bolster cross-border coordination. Sources also state the treaty targets organised crime, framing it as part of the broader security agenda covered by the pact. Starmer is quoted as hailing the deal as a “generational uplift,” suggesting the government views it as a long-term step rather than a short-term arrangement. The reporting is consistent that the leaders sign the treaty following discussions between the UK and Poland, with the package presented as combining defence cooperation with efforts to address serious crime. The outlets do not provide detailed terms of the treaty beyond these stated aims.
