Conservatives in the UK are desperate to get a deal with the 3rd party (and perhaps others) to form some sort of governing coalition, because most Brits feel a "hung Parliament" (Minority Government) would not allow the nation to function properly in these tough economic times. They feel a stable, steady hand is necessary.
Canada has more or less exactly the same system of Parliament. Here, by some sort of dimented train of thought the Conservatives have managed to convince quite a few Canadians that such a configuration - reflecting a government representing a majority of Canadians' voting choice - is somehow illegal.
Can't wait to see what type of "unholy alliance" the Brits come up with - and how Harper and his minions wince when it occurs!
