If it was the fault of the hon. Member for Beverley and Holderness that we descended into partisanship, credit should go to the hon. Member for Warrington South for raising the tone once again, bringing us back on topic and pointing out that it is important that the UK shows leadership in this area. Perhaps we can all agree on that, even if we do not agree on the extent to which that is currently being displayed by the Conservative Government.
As I said, this has essentially been a very successful innovation. One problem—we have had differences of opinion about this during the debate—has been the restrictions placed on the Green Investment Bank in relation to borrowing. Obviously, the Treasury does not want that to appear on the books, because of the targets that it has set in relation to deficit reduction. However, we have come to a strange pass when even something that we could all agree would be a good thing, even good borrowing, is bad if it is on the Government books, simply because it is on the Government books. Hon. Members touched on this during their contributions. Sometimes in this country we seem to be the prisoners of public accountancy convention, rather than common sense, in relation to when borrowing is a good and effective thing to do—when it is to invest to grow our economy in the future in a sustainable way.
