I think local representation works reasonably well now. I would agree with Professor Macfarlane that the implications have to be thought through pretty carefully, because you're making things much more complex. For instance, who's got responsibility for riding interests in a multi-riding?
You, as members of Parliament, have pretty clear ideas of where your responsibilities lie, where your interests lie, and this sort of thing. I think it would be much more difficult to sort a lot of that stuff out under whatever form of PR by which you get elected. There are differences. I don't know the technical part as well as some of my colleagues do, but there are different implications for different kinds of PR. It will affect your jobs in a major way that I've read about. There's been much reflection on this aspect.
