asked the Secretary of State for Defence when he expects to release the full details of the civil defence exercise, Exercise Squareleg, including estimates of the damage and casualties.

Exercise Square Leg formed a part of the military exercise Crusader 80 which took place from 1 September to 4 October 1980. A report on Crusader 80, including Square Leg, was placed in the Library of the House on 16 November 1981. I have nothing to add to it.
