asked the Secretary of State for Defence if he will now supply information on the refusal of the United States to comply with agreements to supply the United Kingdom with UHSIC and stealth technology; and what is the cost of the programmes initiated by the United Kingdom in both technologies.

On the first part of the hon. Gentleman's question, I have nothing to add to the reply given to him on 14 June 1985 by my predecessor, the right hon. Member for Bosworth (Mr. Butler), at column 575. On the second part, it is not our practice to give costs of individual defence research programmes.
