Letter dated 28th May from the Secretary of State to Chair providing an update on the INTERFLEX training programme.

From: Defence Committee

Summary

The Secretary of State updates the Defence Committee on INTERFLEX, the UK's Ukrainian military training programme established in 2022. Having trained over 62,000 recruits, the programme is transitioning from basic infantry training to advanced specialist instruction (tactics, medical, engineering, logistics) under a unified framework, reflecting evolved Ukrainian Armed Forces priorities and building long-term capability.

Key findings

  • INTERFLEX has trained over 62,000 Ukrainian recruits, soldiers, and officers since 2022, with over 11,000 now serving as independent instructors within Ukraine
  • The programme is consolidating all UK-led training (domestic and abroad) under one coherent INTERFLEX banner to improve coordination and strategic awareness
  • Training focus is shifting from rapid basic recruitment to advanced specialist skills including operational tactics, medical expertise, engineering, and logistics
  • The Ukrainian Ministry of Defence has specifically requested more advanced and specialist training to address complex operational challenges
  • The Secretary of State emphasises this evolution reflects sustained UK commitment, not reduced support, adapted to maximise impact and meet AFU priorities
