Question to the Cabinet Office:

To ask His Majesty's Government which Ministers are responsible for ensuring the resilience of critical national infrastructure; and if those responsibilities are split, which ministers are responsible for resilience in each sector.

The UK currently has 13 Critical National Infrastructure (CNI) sectors. Each sector has a Lead Government Department (LGD) that is responsible for sectoral resilience, including risk assessments, policy and guidance and industry engagement. The LGD Minister or Secretary of State for each CNI sector holds overall accountability for their CNI sectoral approach.

The Cabinet Office is responsible for the overarching CNI policy for the UK government, setting strategic cross-cutting priorities and providing assurance to Ministers that LGDs are fulfilling their responsibilities to ensure the security and resilience of their sectors. The Chancellor of the Duchy of Lancaster (CDL) is the Cabinet Office Minister with overall responsibility for Resilience. CDL chairs the National Security Council on Resilience, at which CNI topics are routinely discussed and relevant LGDs are represented.
