PR round the corner?

Voters in British Columbia will have the opportunity next May to vote on a move from the current first-past-the-post electoral system to a form of proportional representation known as the single transferable vote. Not everyone is happy with this. The Greens would like to adopt a mixed-member-proportional system, which is what I myself would tend to favour. If the measure wins, we shall see how the parties in that province go about adapting our hallowed constitutional principle of responsible government to a situation in which no single party wins an absolute majority of seats in the legislature. If the experiment is a success, the rest of the country could follow suit.
