HC Deb 28 October 1976 vol 918 c325W
Mr. Powell

asked the Secretary of State for the Home Department whether he is satisfied with the measures taken on the position between Northern Ireland and the Irish Republic, or otherwise in Northern Ireland, to prevent or detect the entry of persons previously deported from the United Kingdom.

Dr. Summerskill

While citizens of the Republic of Ireland who return to any part of the United Kingdom in breach of a deportation order are removed when detected, we do not consider that costly preventive measures would be justified.
