George Osborne told the BBC's Today programme earlier this morning that he does not want to "let Whitehall off the hook" when it comes to making savings in the spending review.
My central assumption in this spending review is that this is money I am now looking for which is coming out of Whitehall departments, that we have already found billions of pounds of welfare savings this year and we have got to make sure that Whitehall is not let off the hook, that there are still substantial savings - better value for money we can get for taxpayers' money out of the machinery of government.
