Scotland Bill

I certainly agree that the Government Expenditure and Revenue Scotland—GERS—survey is based on certain assumptions and calculations. Most of the documents, certainly over the past decade, have effectively taken the GERS assumptions and, if they have differed from them, have always explained why. Those differences tended to be marginal. The key question here is not SNP figures versus those of another party; it is the work done by organisations such as Oxford Economics or, about a year ago, Reform Scotland, which calculated a broadly balanced budget of about £50 billion out and £50 billion in. Those seem to be generally accepted pre-recession figures.
