The Barnett Formula.....

.....is designed to bring "gradual convergence in spending levels between Scotland and England." Former Tory Scottish Secretary, Ian Lang, says here that:

Scotland should have a fuller role in the overall economic decision-making process in the UK and in the Chancellor's annual budget decisions.

But the economy is not a devolved matter. It is dealt with at the UK level - as it happens at the moment by a Scottish Chancellor. If Mr. Lang wants a specifically Scottish input on economic matters, he should be calling for full fiscal freedom - that is for all taxes paid by Scots to be levied and collected by the Scottish parliament with suitable sums being sent to London for defence and any other non-devolved matters. Only then will Scottish politicians be made to act responsibly.
