I very much respect what my hon. Friend says. He took part in a Westminster Hall debate on the issue, and I am sure the Chancellor and other colleagues are listening to him. We need to be clear, though, about whether he is arguing for a needs-based assessment across the whole UK. Anas Sarwar drew attention to the fact that there are significant differentials within England. The difference between the highest and lowest per capita public spending in England is £2,537, which is much greater than the difference between the Scottish and English average. We need to be clear about whether my hon. Friend and those who make the same argument want a change in spending within England, or just between the constituent parts of the UK.
