HC Deb 26 October 1967 vol 751 c517W
3. Mr. Hugh Jenkins

asked the Secretary of State for the Home Department upon what estimate of the number of survivors in the event of a major nuclear attack on this country he bases the civil defence of the United Kingdom.

Mr. Ennals

The number of survivors would depend on so many variable factors that no worthwhile estimate can be given. The Government is nevertheless satisfied that on any reasonable assumption there would be millions of survivors, and that sensible plans for Civil Defence would add greatly to their number.
