Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, with reference to page 11 of the National Security Strategy 2025, published on 24 June 2025, what progress she has made in enhancing the resilience of critical national infrastructure.

The UK Government is committed to building the security and resilience of UK critical national infrastructure (CNI). On 8 July this year, the Government published the Resilience Action Plan, which sets out this government's strategic approach to increasing the UK's resilience against the risks the UK faces.

To improve CNI resilience, UK Government has committed to continue delivery of CNI Knowledge Base - the UK government’s world-leading CNI mapping tool; map and fully use the complex network of reserved and devolved standards for CNI sectors, which are fundamental in holding industry to account and assuring the resilience of UK CNI; develop a new Cyber Resilience Index to build on existing cyber resilience measures to provide a cross-sector, holistic overview of cyber resilience for UK CNI; and raise resilience by using UK government resources, including the expertise of our National Technical Authorities (including National Cyber Security Centre and National Protective Security Authority), to provide world-leading advice on security and resilience best practice directly to businesses.
