HC Deb 20 December 1915 vol 77 c26
55. Mr. R. McNEILL

asked the Secretary of State for the Home Department how many registered enemy aliens have left their registered place of residence and cannot be traced by the police?

The SECRETARY of STATE for the HOME DEPARTMENT (Sir John Simon)

Figures are not available, but the constant touch with registered alien enemies which is kept by the police indicates that the numbers are very small and that such disappearances as have occurred took place early in the War, before the machinery both of the police and at the ports was in complete operation.
