HC Deb 10 December 1979 vol 975 c421W
Mr. Marlow

asked the Secretary of State for the Home Department what is the proportion of visitors to the United Kingdom which is subsequently checked for possible overstaying, the proportion of those so checked which has in fact overstayed and the proportion of those which has overstayed which cannot be located within a three-month period; and what is the proportion of those which is located which is subsequently deported.

Mr. Raison

I regret that this information is not available. I referred to the problem of overstayers in the course of the debate on 4 December. It is the normal practice to report those overstayers who are detected and who have no claim under the immigration rules to remain and do not leave voluntarily.
