HC Deb 20 March 1952 vol 497 c224W
76. Mr. Driberg

asked the Secretary of State for the Home Department by what authority passengers arriving at airports are required to produce their passports or other identity documents for inspection by officers of the Special Branch of the Criminal Investigation Department.

Sir D. Maxwell Fyfe

Immigration officers are empowered by the Aliens Order to call on a passenger to produce such information and in such manner as the immigration officer may require for the purpose of ascertaining whether the passenger is or is not an alien. In addition, police officers at ports have certain duties to perform in the exercise of which they invite passengers to produce their passports or other documents of identity
