I keep hearing the Green party pushing for proportional representation. as far as im concerned, this is basically an acknowledgement that they are a fringe party, because proportional representation is designed to allow the fringes to backdoor their way into parliament.
I came across this a couple of weeks ago, its called alternative vote, and sounds like a much more interesting idea to me.
