HC Deb 05 December 1972 vol 847 c391W
Miss Quennell

asked the Secretary of State for Foreign and Commonwealth Affairs what system of calculations and methods he has used to obtain estimates of the numbers of people in independent Commonwealth countries whom the United Kingdom might be obliged to admit should they be expelled from their homeland.

Mr. Kershaw

The figures are obtained from the countries concerned and represent the best estimates British High Commissioners there can make from the information at their disposal of numbers of United Kingdom nationals in the country concerned who are subject to immigration control in this country. In compiling the estimates the High Commissioners draw on their own records, official census figures of the countries concerned and whatever other sources may be available to them.
