HC Deb 21 May 1981 vol 5 c126W
Mr. Cartwright

asked the Chancellor of the Exchequer what is his estimate of the number of foreign nationals employed in the United Kingdom by overseas companies who receive income tax concessions because they are regarded as being non-domiciles in the United Kingdom.

Mr. Peter Rees

I regret that it is not possible to estimate the number of such individuals because the law under which these deductions are given does not distinguish between British subjects and others.
