asked the President of the Board of Trade, what countries, other than the United States of America, compel transit passengers in British aircraft passing through their airports to submit to customs, immigration, and health procedures.

Australia. Malagasy Republic, Mexico, Poland and Thailand have notified the International Civil Aviaton Organisation that in this respect they are unable to comply with Annex 9 of the Convention. There are other countries, however, which have not formally notified I.C.A.O. of a difference but which, I understand, require some examination of transit passengers.
