HC Deb 12 April 1984 vol 58 c355W
Mr. Frank Cook

asked the Secretary of State for Defence how many times there has been an actual attack warning red alert involving British forces or North Atlantic Treaty Organisations forces based in the United Kingdom.

Mr. Stanley

There has been no warning of an actual imminent attack on the United Kingdom since 1945, nor have British or allied forces in this country been deployed to react to one.
