Thank you, Mr. Chair.
Thanks to both witnesses. Here in Edmonton we've had extraordinarily fine testimony. I don't know if you were here earlier for Sean Graham's presentation on dual-member proportional. I just wonder if I could ask each of you—and forgive me if you've already touched on this—what you thought of that system. We have two advocates before us who want proportional fair voting, one who favours mixed member proportional and one who favours STV. I think you're very familiar with the merits, the pluses and minuses of other systems.
Have you looked at dual-member proportional before, and what did you think of it?
I'll ask Professor Nash first.
