HC Deb 21 January 1980 vol 977 c80W
Mr. Leighton

asked the Secretary of State for Defence what proportion of British industrial research spending is directed at defence.

Information in the form requested is not available. However, in 1975,the latest year for which comprehensive information is available, it is estimated that approximately one-quarter of industrial expenditure on both research and development in the United Kingdom was directed at defence.
