Yes. If you read through the law commission report, I think I counted 13 times where it says that their goal was to add an element of proportionality to our current system. By definition, that's either MMP or MMM. That's where they started. In their discussion of the different systems, they described STV in a reasonable way. Then they decided, in one sentence, that they were not choosing STV, because there was multi-member districts. Of course, not having multi-member districts.... Single member districts is the root cause of so many of our electoral problems.
