Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether his Department has identified which categories of critical national infrastructure should be prioritised for protection under the UK’s integrated air and missile defence planning.

Defence is working with the Cabinet Office to prioritise and protect Critical National Infrastructure (CNI). Defence is capturing data on a CNI knowledge base, which helps government understand the priorities and vulnerabilities between the 13 CNI sectors. This tool is contributing to Defence work to refresh our homeland defence plan as a priority for 2026.
