The House will remember that there was some talk at one stage of a Commonwealth citizenship. Now it was difficult to understand what the contents of a Commonwealth citizenship might be, except that it meant that they were not completely foreign to one another. That un-foreignness remains, but I think it is as well that we left off talking about something vague, which could not be surely defined, but the other fact remains, as I have just stated: the fact that we should take the right to ourselves, if we so chose to exercise it at any time, to enter into treaties or arrangements with Commonwealth countries assuring certain mutual privileges and preferences.
