whilst there is many different forms that PR can take i really doubt any would suit the party in power. just because the tories are in power it does not mean this FPTP system is the correct one to use. just because something has always been done a certain way in no reason to carry on the same way. might actually get a system where more than two thirds of the electorate actually vote, and the tory in places like barnsley will then know his vote may count.
