Question to the Ministry of Defence:

To ask the Secretary of State for Defence, which offices in his Department are responsible for maintaining and monitoring nuclear security at defence sites.

There are a number of organisations within the Ministry of Defence (MOD) who have responsibility for maintaining and monitoring nuclear security at defence sites. MOD Head Office sets security policy for defence including the requirements for nuclear security. The responsibility for the delivery of nuclear security at defence nuclear sites rests with the Head of Establishment. Nuclear security assurance (monitoring) is delivered through self assurance by the defence nuclear site. Independent assurance is provided through the Principal Security Advisors to Front Line Commands and the Defence Equipment and Support organisation and through MOD Head Office.
