HC Deb 16 April 1993 vol 222 c739W
Mr. McNamara

To ask the Secretary of State for Transport what information is held on the number of delays on British Rail and London Underground caused by security alerts, on a yearly basis since 1969.

Mr. Norris

British Rail and London Underground maintain records of such delays, though not back to 1969. It is not their policy to publish such information and thereby to give publicity to the activities of terrorists.
