HC Deb 03 December 1968 vol 774 c442W
Mrs. Ewing

asked the Secretary of State for Defence what survey his Department has made of the strategic risks involved in siting the Polaris base in the Clyde estuary, with the resulting increase in proximity of Russian nuclear submarines in the same area.

Mr. Healey

Before the site of the Clyde Submarine Base was determined all the relevant factors were taken into consideration. We have no evidence of any Russian nuclear submarines operating in the Clyde area.
