HC Deb 02 April 1985 vol 76 c565W
Mr. Cohen

asked the Secretary of State for the Home Department what is Her Majesty's Government's definition of the term national security.

Mr. Brittan

This term has been in general use for many years in a variety of contexts and is generally understood to refer to the safeguarding of the state and the community against threats to their survival or well-being. I am not aware that any previous Administration has thought it appropriate to adopt a specific definition of the term.
