Yup, but I think PR fosters the emergence of Far Right/fascist parties.

I sort of explained the mechanisms to someone else in this thread here:

tl;dr: FPTP discourages fringe parties, so they can't snowball into something much more dangerous. And PR systems have, in the last couple of decades, had a much harder time passing significant legislation which has led to a general stagnation/dissatisfaction, whereas a system that produces strong majority governments for better or worse, gets a legit chance to pass comprehensive legislation to tackle issues. Carney has 4ish years to try his best to make serious change without having to beg the Conservatives for everything.
