HC Deb 12 May 1972 vol 836 c461W
Mr. Biggs-Davison

asked the Secretary of State for Trade and Industry what are the comparative average rates of return on capital of the private sector of industry in the United Kingdom and the countries of the European Economic Community.

Mr. Noble:

Insufficient data from most EEC countries and differences in accounting conventions prevent the calculation of meaningful comparative rates of return on capital at present.
