§ Mr. Arthur Lewisasked the Secretary of State for the Home Department how he is able to keep a check and make selective checks on people admitted into Great Britain for limited periods to see whether they have left when he has no knowledge of the number of persons who have overstayed, or the numbers of persons of stated nationalities who have entered; and how these checks are operated.
§ Dr. SummerskillThe checks are made by matching embarkation cards, which each passenger who is subject to immigration control has to complete on leaving, with the corresponding landing cards filled in on entry to the United Kingdom. The system is not designed to provide statistics of totals of overstayers.
