## Have countries or electorates that have switched to proportional representation experienced less factional in-fighting?

3

In theory I would imagine proportional representation would reduce backroom factional in-fighting by both bringing disputes into the light of day (the voting booth) and allowing major factions to be the separate parties they often are.

However, what is the evidence in countries or electorates that have switched to proportional representation (MMP or otherwise) that they've had less factional in-fighting?
