Indeed I had remembered the results of the last election which led to a minority SNP government.
There was a TV interview a few years ago with Annabel Goldie, former leader of the Scottish Conservatives in the Scottish Parliament where she was very proud of the way the Scottish Parliament worked. As 4th party in terms of members she was still able to get through some key policies because the parties all worked together to create a consensus of governance. In return for getting some of their more sensible policies implemented, they agreed in principle to not unreasonably oppose sensible things put forward by the governing party. She also highlighted a few policies where the Tories had suggested an amendment to SNP bills and the bills were amended because everyone else accepted them as sensible. Even now as a majority of SNP the smaller parties still get things through regularly.
There's no way that would work in the UK Parliament, if you're not in the governing party (or parties) then you get nothing beyond the ability to rant in public in the House. If Cameron stood up today and said it was Tuesday afternoon, you'd probably get at least one senior MP on the other side (or even his own) putting forward an amendment to recognise that it's Wednesday morning in some parts of the world.
