My Lords, the point about not passing through immigration control occurred to me as well as noble Lords were speaking. Then my mind turned to the question of what would happen if someone was travelling on one passport but carrying the passport of another country and switched half way through the journey. All this goes to the workability of these provisions, which is really the overarching question that noble Lords are asking. I do not think that I am alone in finding it a little difficult to imagine quite how the powers will operate in some circumstances.
It is not always easy to probe something without suggesting the opposite of what one intends. There is another example of that coming up shortly. So the noble Lord is right: I was not trying to take the words out but merely probing.
I am not sure—I may have missed it—whether the Minister referred to international organisations other than quoting what is in the schedule. Perhaps I may look at that after today and, if necessary, have another word with him. It looks as though I may not need to withdraw the amendment quite yet.
