HC Deb 19 March 1973 vol 853 c8W
Mr. Loveridge

asked the Secretary of State for Trade and Industry what proportion of the United Kingdom gross national product is accounted for by the following groups of industry: (a) the 1–10 companies with largest output, (b) the 11–100 companies with next largest output, (c) the 101–200 companies with next largest output, and (d) the 201–500 companies with next largest output; and what proportion is accounted for by each of the nationalised industries.

Mr. Emery

This information is not easily available and to obtain it would cause disproportionate cost.
