I am going to make a little progress, again mindful of the guidance that I have received. Leaving the EU will not diminish our commitment to environmental principles. Indeed, it is an opportunity to reinforce them. My right hon. Friend the Secretary of State for Environment, Food and Rural Affairs, who was here earlier and I am sure is coming back, announced only last week our intention to publish a new comprehensive national policy statement setting out the environmental principles driving UK policy, drawing on the EU's current principles and underpinning future policy making. The point about its relative significance, value and status was very well made by my right hon. Friend the Member for West Dorset (Sir Oliver Letwin). I ally myself with his remarks. We will consult on it early next year. This is not just blue-sky thinking-it is coming imminently. Critically-this touches on the point made by the Chair of the Select Committee-the Secretary of State has also set out plans to consult on a new independent statutory body to hold the Government to account for upholding environmental standards. I hope that that addresses concerns that some hon. Members may have not just about the substantive law but about the institutional checks and oversight that we definitely need to make sure we continue when Britain leaves the EU. I hope that addresses the point that hon. Lady made, which was also mentioned by the hon. Member for Brighton, Pavilion. Turning to amendments 60, 67 and 28, I certainly understand their intention, but they are unnecessary because of the snapshot of all EU environmental principles that we are already taking at exit day under this Bill. Furthermore, the amendments would alter existing EU principles, at least to some extent-for example, in the way that they apply to public authorities. Given that the Bill's purpose is to bring into effect the law we have currently, the amendments risk generating a measure of uncertainty and a degree of confusion about the legal position. I hope that I have addressed some of the concerns on the environment, and I urge hon. Members to not to press the relevant amendments. I turn to amendment 93 in the name of the hon. Member for Bristol East (Kerry McCarthy). Many hon. Members have been eloquent in outlining the need to ensure that treaty rights and other provisions falling outside clauses 2 and 3 are still retained in UK domestic law. Clause 4, as I have said, is a broad sweeper provision. It will ensure that as a starting point, all existing rights available in domestic law immediately before exit day as a result of section 2(1) of the European Communities Act 1972 will continue after exit to be recognised and available in our domestic law to the extent that they were before exit day. Clause 4(1) deliberately mirrors the language in the European Communities Act, which for our period of membership of the EU has been used to determine what and how EU law is accurately reflected in UK law. Clause 4 goes no further than section 2(1) of the ECA currently does. It is not intended to capture a narrower set of rights or obligations, or somehow to trim back. It does not make any changes as to how those rights or obligations are enforced in our courts. Deleting clause 4(1)(b) would mean that clause 4 no longer mirrors the ECA. I understand why the hon. Lady has tabled the amendment, but it would be a rather curious, if not perverse, outcome if what counted as EU law after we depart the Union was expanded to be wider than when we were a member-yet that would be the direct result of her amendment. Perhaps even more importantly, for individuals, businesses, courts and practitioners up and down the country, by changing and inflating the test for what counts as EU law just as we are leaving, the amendment would in practice lead to significant legal confusion after exit with regard to the scope of rights retained. I know that that was not the intention of her amendment, and I hope that she can be persuaded not to press it.
