The National Security Strategy

Inquiry

The Government published a new National Security Strategy (NSS) on 24 June 2025.

The NSS reviews the risks facing the UK and sets out plans to address them, structured under three themes: security at home, strength abroad, and sovereign and asymmetric capabilities.

The Committee is seeking views on how well the NSS addresses the range of challenges facing the UK. The Committee is focusing on priorities, delivery and accountability - with an emphasis on the adequacy of arrangements for cross-government co-ordination,  timelines, funding and responsibilities.

This inquiry is no longer accepting evidence

The deadline for submissions was 11:59pm on 18 September 2025.
