Overview
- The agreement was signed Wednesday by Prime Ministers Keir Starmer and Donald Tusk at a former military site in northwest London and formalises deeper UK–Poland defence ties.
- It commits both governments to large-scale joint military exercises and expanded use of unmanned systems to protect NATO’s eastern flank.
- A central element is a programme to jointly develop and produce next‑generation complex weapons systems, with procurement and production arrangements to be worked out in coming months.
- The pact also broadens cooperation on cyber defences, organised crime, migration, energy and health, creating formal channels for information sharing and joint projects.
- Poland’s recent boost in defence spending and the UK’s wider run of bilateral deals with European partners frame the pact as part of a push to deepen security ties and deter Russian aggression.
