Scotland Bill

One second. I am sure that such a change will not be allowed to happen, but UK Governments have announced 17 changes to income tax since 2007, and they would have affected the proportion of income tax revenue or receipts assigned to the Scottish Government. Those changes included not only the big headline splash on the £10,000 threshold, but 16 others, each of which would have affected the assignation of receipts to Scotland. Even if the provisions did not result in a real-terms cut to the Scottish budget, which I believe they do, and even if they did not create an in-built deflationary bias, which I believe they do, they would still provide an unstable platform for the Scottish Government, precisely because of the volatility of income tax receipts in difficult times. At no time was that clearer than between 2007-08 and 2009-10, when income tax receipts fell by 7.3%. Over those two years, that would have led to a drop in Scottish revenue in excess of £1 billion, and that is presumably the point at which the revenue-borrowing powers are meant to kick in and help. I shall take the hon. Gentleman's intervention now, because the next part of my speech is complicated.
