HC Deb 19 June 1980 vol 986 c610W
Mr. Ray Powell

asked the Secretary of State for the Home Department what system the Government would use to warn every person in the United Kingdom of a nuclear attack ; and if he is satisfied that arrangements in this regard are adequate, efficient and not totally dependent on computers.

Mr. Whitelaw

The public warning system operated by the United Kingdom warning and monitoring organisation does not involve computerised procedures. I am considering, as part of my present review of home defence arrangements, what improvements in the system may be called for.
