HC Deb 11 May 1961 vol 640 c642
47. Mr. Marsh

asked the Prime Minister if he is aware that United States documents concerned with secret experimental work on underwater warfare, entrusted by the Admiralty to one of their contractors, have been lost or stolen; and if he is satisfied with the action that has been taken in this matter.

The Prime Minister

Documents of the kind described are missing at a contractors' works. A thorough investigation has been made and the circumstances indicate that the documents are more likely to have been mislaid than lost or stolen.
