Suddenly, a Liberal Democrat appears

I sure do hope for you guys can make the switch to PR as you are suggesting might happen. I don't know the intricacies that differentiate your government from the one we have here in Canaduh-land, but if it's as I understand it, I wouldn't hold my breath on the PR system actually getting implemented.

The New Democratic Party (our third biggest party, similar to your LibDems) have had switching over to PR as part of their platform for quite a while now. The problem is that the two main parties have absolutely no reason to want to switch over, as they would just lose power in the process. Hence, they will do whatever it takes to make sure it is never put to a vote. Granted, if a coalition government is formed with a large enough number of LibDem MPs, whoever forms the other half might now have no choice but to at least discuss the possibility.

Jam it back in, in the dark.
