HC Deb 13 July 1989 vol 156 c590W
Mr. Wilson

To ask the Secretary of State for Defence if he will list, by geographical area, the number of second world war explosive devices which have been discovered in British coastal waters in each of the past 10 years.

Mr. Archie Hamilton

Precise records of the number of such finds in each of the past ten years are not maintained. Each year, however, some 30 or 40 mines and 100 torpedoes, bombs or large calibre shells of world war I or world war II origin are found in British coastal waters.
