HC Deb 16 October 1995 vol 264 c42W
Mr. Martyn Jones

To ask the President of the Board of Trade, how many public interest certificates his Department has issued in each year since 1986. [36688]

Mr. Lang

My Department's records show that, since April 1992, 21 public interest immunity certificates have been signed by Ministers of this Department, five of which did not need to be deployed. No central record is kept of certificates signed before that date.
