Executive Summary

Since its creation in 1964, Defence Intelligence (DI) has been a cornerstone of the UK’s national intelligence framework. Evolving through the integration of military and civilian intelligence entities. As DI marks its 60th anniversary, this milestone offers a moment to reflect on its legacy of critical contributions to the UK’s defence and global security. More importantly, it highlights the ongoing need for modernization to counter emerging threats, such as data-driven warfare, cyber espionage and attacks, and strategic competition among great powers.

DI collaborates with key national intelligence agencies, including GCHQ, MI5, and MI6. To deliver timely and actionable intelligence for UK defence and government decision-making. Looking ahead, DI remains essential to the UK’s security, poised to strengthen its role through digital transformation and advanced intelligence capabilities while building on its historical strengths.
