To ask the Secretary of State for Trade and Industry what is his estimate of the proportion of total European single market trade which will be British-originated in 1992; and if he will make a statement.

Given the changes which will follow he completion of the single European market, I cannot make a useful estimate of the proportion of total single European market trade which will be British-originated in 1992. The United Kingdom's share of EC trade was 8.9 per cent. in 1973, the year of our accession. It has risen to 13.1 per cent. in 1983 and stood at 11.4 per cent. in 1988. These figures assume current membership of the EC at each date.
