HC Deb 12 January 1989 vol 144 c718W
Mr. Foulkes

To ask the Secretary of State for Transport what inquiries or investigations have been carried out into the sinking of the Ardlough, Ocean Gain, Mhari-L, Alert II, St. Patrick, Emma Jane and Inspire; what has been the result of such inquiries or investigations; which of the incidents took place in submarine exercise areas or normal submarine lanes; and if he will make a statement.

Mr. Portillo

Inquiries were carried out by the Department's marine surveyors into casualties involving Ardlough, Ocean Gain, Mhari-L, Alert II, Emma Jane and Inspire, but not the French flag vessel St. Patrick. Of those investigated, only the Ardlough and Mhari-L were in a submarine exercise area. The positions of submarine lanes are classified information.

The surveyors found no evidence of submarine involvement in any of the cases investigated.
