What goes around comes around.
Exactly the opposite. PR can lead to stability with fewer lurches from one party rule to another, less anger about being under represented, more voices being heard and more respect for the process....
The real risk is that PR would bring with it a decade of instability which would make Brexit fall out seem trivial by comparison.
Yes the tories could lose by it as things stand but this wouldn't always be the case. ALL parties would find themselves having to take note of the others without betting all on a desperate grab for total power.
