Question to the Cabinet Office:

To ask Her Majesty's Government what steps they are taking to protect critical national infrastructure from potentially hostile states, particularly in the nuclear sector.

Critical National Infrastructure (CNI) in the UK, including the Civil Nuclear sector, is subject to thorough scrutiny and must satisfy stringent sectoral regulatory and national security requirements. For the Civil Nuclear sector specifically, the Office for Nuclear Regulation independently oversees and enforces the UK’s nuclear regulatory regime.
