Before I withdraw the amendment, may I say that I am immensely grateful to my noble friend for his reply to the debate? I—and others, I am sure—will want to study carefully what he has said, because this represents, in some respects, a new departure in trying to assess who is actually having to pay for the huge programme of infrastructure investment on which we are currently embarked.
I thank the noble Lord, Lord Berkeley, and I should also mention that the noble Lord, Lord Whitty, apologised to me for the fact that he had to leave. This has been a useful debate, and I am grateful to my noble friend for having been here to reply to it in the way that he did. I beg leave to withdraw the amendment.
