Asked

Without revealing personal information, how many applicants for Developed Vetting in 2025 were assessed as (a) clearance approved, (b) clearance approved with risk management, and (c) clearance denied or withdrawn.

Reply

National Security Vetting (NSV) clearance applications, including Developed Vetting, are rigorously assessed within a robust governance framework. UKSV works closely with departmental vetting risk owners to balance operational demands with assured and effective national security safeguards. In line with the practice followed by successive administrations, the government does not otherwise comment on security matters. To reveal such details could prejudice national security and would provide insights into the scale and nature of the UK’s sensitive workforce and the thresholds of our security safeguards.

Asked

What assessment the Investment Security Unit has made of the effectiveness of (a) the Planning Inspectorate and (b) Nationally Significant Infrastructure Project processes to safeguard against national security risks from investment by (i) inappropriate or (ii) hostile overseas sources.

Reply

The Investment Security Unit in the Cabinet Office is responsible for administering the National Security and Investment (NSI) Act 2021, which provides robust investment screening powers for the Government to scrutinise and, where necessary, intervene in acquisitions which could present a risk to the UK’s national security. If required, the Government has the ability to impose conditions, block or unwind acquisitions.The Government welcomes investment as part of our mission to boost growth, but only where it meets our regulatory requirements and does not compromise our national security. We will not hesitate to use our powers to protect national security where we identify concerns.
