To ask the Secretary of State for Defence what information he has on the value of sales of military equipment by United Kingdom companies in each year since 1979–80 (a) within the United Kingdom, (b) to other EC countries and (c) to non-EC countries, in (i) cash and (ii) 1992 prices.

To answer the question precisely as asked would involve disproportionate cost. I will, however, be happy to write to the hon. Member on this subject.
