Chris.....I am not sure if that is true but even if it is, what is the difference between that and 2010 ?
You could argue that all Governments are a coalition of some sort. Even a Party with a working majority, still sometimes needs the votes of minor parties, in order to be sure of getting legislation through. And not all legislation is opposed.
But it looks as the SNP are going to be a major opposition Party in a few days time. The Scots are entitled to vote how they wish. If they abandon their normal choice of Labour and vote SNP...so be it...that is how democracy works !
