I will give way again, but first let me make some progress.
It is simple: the pooling and sharing of resources across the UK, and the maintenance of the Barnett formula, benefits Scotland. The much-quoted Institute for Fiscal Studies, which the SNP continually rubbishes, has demonstrated beyond argument that full fiscal autonomy would result in Scotland having a deficit of some £7.6 billion. Before SNP Members jump up to challenge those expert figures, I want to put it on the record that that is over and above any current UK deficit and UK spending projections.
