HC Deb 04 March 1982 vol 19 c206W
Mr. Meacher

asked the Secretary of State for the Home Department on how many occasions in each of the last five years surveillance devices have been operated in each of the 43 police force areas under the bugging code he published in the week ended 26 February.

Mr. Whitelaw

I regret that this information could be obtained only at disproportionate cost.
