Government Back Benchers are as baffled as I am by the shadow Chancellor’s economic policy, which he has just had a few minutes to explain and still there is no explanation. His answer to a debt crisis is to borrow more. His answer to too much borrowing is to add to it. That is the problem he has, ultimately—that he is responsible for the mistakes that got Britain into this economic mess. This is the verdict from the leading Citi economist, Michael Saunders, today:

“In our view, the underlying causes of the UK economy’s weakness—and hence the rating downgrade—stem from the surge in private credit and public spending during 2000-2007.”

Who was in charge of economic policy during that period? The right hon. Gentleman is the architect of the mistakes that gave Britain its debt problem. He ignores the solution to that debt problem. He is condemned to repeat those mistakes and, as a result, his party is condemned never to be trusted with the public finances again.
