asked the Secretary of State for the Home Department if he is satisfied with the arrangements to prevent illegal immigration through overstaying.

Developing the effectiveness of the arrangements to counter overstaying is an objective to which the Government attach importance. The introduction of a computer later this year should improve the efficiency of the selective checks made on the departure of people here temporarily. Further progress will depend in part on the resources available in both the Home Office and police forces for following up cases of suspected overstaying. The immigration service has recently been devoting more time to assisting the police in such inquiries.
