Finance Bill

My right hon. Friend is forging a progressive consensus with the hon. Member for Nottingham, South (Alan Simpson) to which I am a happy subscriber, but I am puzzled and my brow is furrowed. Can my right hon. Friend explain to the House why there is an instinctive disinclination on the part of the Treasury annually to report? Is it because the Treasury thinks that others report to it and that it is not in the business of lowering itself to report, or is there a better reason that has hitherto escaped me?
