§ Mr. Alan Clarkasked the Secretary of State for Defence how many unidentified traces of submarine activity have been recorded by ships of the Royal Navy in the last year; and whether any of these have occurred inside United Kingdom territorial waters.
§ Mr. Robert C. BrownUnidentified traces of underwater activity detected by the Royal Navy world wide are to numerous to justify recording. I can confirm, however, that no unexplained submarine contacts have been made within UK territorial waters during the last year.
