Retained EU Law (Revocation and Reform) Bill

My Lords, as I expected, the Minister is giving a very satisfactory list of assurances that he has not the slightest intention of lowering any standards. I am quite sure that he is sincere and that the Government actually believe that they are not going to lower any of those standards. I cannot understand what the argument is against ending this whole ridiculous debate by just putting a statement in the Bill which lists key directives—such as the habitats directive and the bathing water directive—and emphasises that they are going to remain totally unchanged, so that if any future Government decided to start deregulating in this area, it would need a proper parliamentary process before they had any chance of doing so. What is the positive argument against putting these undertakings, which are wholly reassuring, in the Bill? The last hour and a half would have been quite unnecessary if that had been done.
