asked the Secretary of State for Transport why several private cars and other vehicles were using the as yet unopened M25 interchange at Leatherhead at 10 am on Wednesday 1 May; and if he will make a statement.

Advertising agencies, film companies and so on often ask to be allowed to use unopened stretches of motorway which are not yet ready for use by public traffic, for filming or demonstration purposes. The Department gave permission for London Weekend Television to use part of the Leatherhead interchange section of the M25 on 1 May 1985.
