My Lords, as I have tabled an amendment to the amendment moved by the noble Lord, Lord Turnbull, I believe that it is for me to withdraw my amendment first and for him to follow. The noble Lord, Lord Deighton, has two objections to the process of review, both of which have, I think, been demonstrated to be false. He said that the first was to secure consensus. From the discussion today, he should be effectively disabused of the idea that the ICB has secured consensus. People have settled around the ICB as the best that can be obtained under the current circumstances, but there is a considerable degree of uncertainty about whether the ring-fence is actually a good idea.
The noble Lord also said that he wanted certainty, but he absolutely does not get certainty in this way because we are very uncertain as to whether this system will actually work. That is why his second objection—that time should be given for the system to settle down and work—is a very dangerous one. As we go through the process of implementation—if eventually Parliament agrees to these ring-fence proposals and implements them—we will discover by sheer practice where the lacunae may be, where things simply go wrong with unintended consequences, and so on. Unfortunately, we will be conducting an experiment and under those circumstances, it is very important that the sort of expert committee that the noble Lord, Lord Turnbull, has proposed, focusing on the particular question of whether this works, with growing expertise and experience, should be in place to review what is happening as the process unfolds.
That is why in particular I was very nervous about one aspect of the proposals of the noble Lord, Lord Turnbull, with respect to the review not taking place for four years and then taking place at five-year intervals thereafter. Although it is “up to” four years, I would be willing to bet that the “up to” will turn out to be about two. None the less, my amendments were intended to ensure particularly that we have the expert committee proposed by the noble Lord, Lord Turnbull, virtually in place as a standing committee with the expertise to guide us through what is going to be a very difficult and uncertain process.
Given the debate, and the views expressed around the House, this is a matter to which we certainly must return after significant negotiations have occurred between Committee and Report stages to try to achieve something of a consensus—at least on the issue of the nature of review. In the mean time, I beg leave to withdraw Amendment 4.
