This may be the easiest intervention I get today, but I do agree that everything is on the table and that everything is possible. In fact, if the hon. Gentleman listens closely as I develop my speech, he will find that I am rather sympathetic to taking further steps toward financial devolution, which the hon. Gentleman and his colleagues have proposed.
Equally, there needs to be recognition that with greater financial freedom and power, Scotland must expect to bear some additional responsibility. I am sure that as a matter of principle—regardless of the practicalities—all hon. Members would agree with that. A new deal for Britain must be fair to all parts of Britain. In my view, that means two things. First, if we went down the road of devo-max or fuller financial devolution, it would eventually render utterly untenable the Barnett formula used by the UK Government to subsidise the devolved Administrations. That formula is based on outdated spending patterns and population numbers and is already divorced from any objective assessment of real need across Britain. If Scotland now wants greater powers to tax and spend—as I said, I am sympathetic to that—it cannot expect the Union and taxpayers across the Union to keep subsidising them to the hilt on such an arbitrary basis, without fuelling resentment in other parts of the UK. I note that that is also the logic of the SNP submission to the Smith review. I have it here and will happily read it later.
