Immigration Controls

I expect that I know rather more about the Canadian system than the hon. Gentleman knows about the Australian system, and they are very similar. I lived in Canada for nine years. I was an immigrant in Canada. Internal controls do not work unless one is prepared to say to immigrants, using the hon. Gentleman's kind of example, ““You can have your job in Scotland, with one employer, so you can't leave that employer””—it is like slave labour—““and for ever more.”” That is the problem with the system that he is proposing. If people are given a time limit, as they certainly should be given in anything like such a system, within four years they will all move, as it were, from Scotland to London.
