Written question to the Office of the Secretary of State for Wales from Hemsworth MP Jon Trickett.
Question: To ask the Secretary of State for Wales, how many people holding security passes for other Government Departments are granted access to his Department's premises with that pass, by Department. (Jon Trickett)
Answer: Civil Servants have the ability to work flexibly across government sites where there is a business need to do so. The issuing of all passes is controlled by the local Departmental Security team who follow strict procedures and protocols. Information on the number of people holding security passes for other government departments who are granted access to Wales Office premises is not centrally recorded. (Guto Bebb, Parliamentary Under Secretary of State for Wales, Lord Commissioner of HM Treasury)
