Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether the Defence Nuclear Safety Regulator has amended his advice on when high security vehicles for transporting special nuclear materials should be withdrawn from service; and for what reasons those vehicles continue to be used after their retirement date.

The High Security Vehicle was withdrawn from service on 31 July 2015 and has therefore not been used for operations since that date. The decision to withdraw the vehicle was taken by Defence Equipment and Support. I am withholding further information as its disclosure would, or would be likely to prejudice the capability, effectiveness or security of the Armed Forces.
