HC Deb 11 February 1985 vol 73 c53W
Mr. Deakins

asked the Chancellor of the Exchequer what change in the overall competitiveness of the United Kingdom economy has occurred as a result of United Kingdom Membership of the EEC.

Mr. Ian Stewart

It is impossible to quantify the effects of United Kingdom membership of the European Community on general competitiveness. However, the United Kingdom has benefited from access to the large Community internal market because of the opportunities for greater specialisation and exploitation of comparative advantage which a larger market affords.
