My Lords, the noble Lord should be rather careful about drawing comparisons between the EU as a place to travel and to work in, and Australia and Canada. My son studied in Canada, where there is a strict visa system for students: you have to leave as soon as you have finished your course,
and he had to be very careful to get himself out of the country before his permission ran out. You need a visa even to visit Australia, and I suspect that it also has rules for visas if you have to work there. Of course people go there, and that visa system is comparatively relaxed, but it is not the same as the freedom we have in the EU.
