I thought I was being pretty specific.. this ability to combine your parties to form one big alliance to take over and claim you have the majority.
Well, that's what I was getting at. If this were to happen, we're no longer a parliamentary democracy. A party or group of parties has to prove they are able to govern before the monarch (or monarch's representative, in this case) will install them as the government. In the case of a majority, that's not a problem, but in a minority situation, the current situation can easily happen (see the Sweden example above). Everyone just presupposes that whoever gets the most seats will automatically form the government, when in fact that has never been the case.
