I entirely agree with my hon. Friend and I am grateful to him for making that point at this stage in the debate. I am glad to say that he is something of an expert on this subject, having been steeped in it for many years. He is absolutely right; it is also very important, for the reasons he has just stated, that we keep the Barnett formula. That is the way to protect the people of Scotland not from the effects of the Conservative-led coalition but from the effects of 13 years of Labour mismanagement of the economy.
