Scotland Bill

Before the hon. Gentleman intervenes, I wish to illustrate that point by discussing two SNP publications that examined the period between 1979 and 1997. In one document, published in October 1996, the SNP estimated that Scotland had contributed £91 billion to the UK over that period. Three months later, however, it published a separate report covering the same period which calculated that the figure had been £27 billion. Well, what is £60 billion between friends? The point is that anyone wanting to analyse this has to do it on the basis of assumptions, not hard facts.
