HM Ships Ocean, Illustrious, Manchester, Cornwall, Cumberland, Portland, Somerset, Northumberland, Richmond, Westminster, Kent, and St. Albans are currently deployed with one or more helicopters.
The documents in question were not MOD property; they belonged to a defence engineering supplier who had arranged for them to be taken to the TNT archive facility in Swadlincote.
The circumstances and the content of the boxes have, however, been examined by Defence Equipment and Support security staff who are satisfied that none of the documents were classified above restricted and did not represent a security risk. I have been reassured that the company have put improved processes in place to prevent a recurrence.
