(Limited Text - Ministerial Extracts only)

Tuesday 3rd June 2025 Written Statements

[The Prime Minister (Keir Starmer)]

I am making this statement to bring to the House’s attention the following machinery of Government changes.

I am today announcing that responsibility for Government and public sector cyber-security will move from the Cabinet Office to the Department for Science, Innovation and Technology. This change will strengthen technology resilience and policymaking across the public sector by better integrating cyber-security responsibilities and expertise into the Government Digital Service. This change is effective immediately.

I am also confirming that responsibility for defence exports promotion—comprising the majority of UK Defence & Security Exports—will move from the Department for Business and Trade to the Ministry of Defence. In line with the defence industrial strategy, this will enable the Government to develop a single defence exports offer, driving a significant and sustained improvement to performance while giving stronger backing to our world-class defence industry. It will directly connect exports with the MOD’s wider procurement and international activity. The creation of a single Departmental lead for defence exports will deliver on the Government’s first mission of delivering economic growth as well as their first duty of protecting the UK. Responsibility for security and cyber exports will remain in the Department for Business and Trade. This change will take effect on 31 July.
