I absolutely agree. The devolved Administrations, as my hon. Friend has reminded me, agree that they want to take a UK-wide approach to this issue, but it would have to be an agreement. Let me turn now to those new clauses and amendments that relate to the Government's proposals about how Parliament will scrutinise and, where necessary, approve secondary legislation made under the powers set out in schedule 7(6). It is clear that the vast majority of hon. Members and the Government have accepted that the House's current procedures for scrutinising negative and affirmative instruments are not acceptable. The hundreds of SIs that will flow from clauses 7 to 9 and 17 need something different. It is encouraging that Ministers have listened and have made it very clear that they intend to accept the amendments in the name of the hon. Member for Broxbourne (Mr Walker) and other members of the Procedure Committee. We welcome those amendments and the establishment, as our new clause 1 proposes, of a parliamentary Committee to sift or triage regulations, and we support their incorporation in the Bill. Frankly, it is better than nothing, but it is the minimum of what might be expected, and we do not believe that they go far enough. Amendments 397 and 398 propose that every SI made only via the negative procedure will be sent to the new Commons committee for consideration, with the committee determining within a 10-day window which ones would be required to be made under the affirmative procedure. That is an improvement on the arrangements proposed in this Bill as it stands, because it provides for discretion beyond the very narrow category of regulations attracting the affirmative procedure currently set out in schedule 7, and it will ensure that Ministers will not have unfettered discretion to decide whether the affirmative or negative procedure should apply in cases where an exercise of powers does not fall within one of the categories set out in the Bill. Ministers must justify why the new committee will not be tasked with looking at SIs made under the affirmative procedure, or with examining the justification for using the SI in question to remedy a particular deficiency in EU law. Importantly, they must justify why, in urgent cases, which I know is a phrase that is undefined, Ministers can simply bypass the committee. Lots of these matters will be dealt with under Standing Orders, but it is right that we press for some clarity today. I hope that the Minister will provide further clarification on the composition of the new committee, in particular whether, as proposed in our new clause 1, the chair will be elected by the whole House and will be, and will be seen to be, independent of the Government. Ministers must further explain why they do not believe that the new committee should have the powers to recommend revisions to individual SIs. Amendments 397 and 398-here I stand to be corrected by the hon. Member for Broxbourne or others on the Committee-make no such provision for revision. In this respect, they differ in a crucial aspect from the proposals set out in the Procedure Committee's interim report of 6 November, which, while not providing for a formal mechanism for revising secondary legislation, did suggest a process by which a request could be made to Ministers to revoke and remake any particular SI underpinned by the scrutiny reserve. Without provision for this House to request, in certain limited cases, that a particular SI be revised, hon. Members will face a Hobson's choice-take it or leave it with regard to regulations that may entail highly significant policy choices and have potentially serious or far-reaching implications, with “leave itâ€ in these circumstances meaning a hole in the statute book. Our amendments 33 to 41 make it clear that any new sifting committee that is established must be given the means not only to determine the level of parliamentary scrutiny that each SI is accorded in proportion to their significance and policy implications, but to make recommendations as to how particular SIs might be improved by revision-if necessary if only by means of the committee in question recommending that an instrument either be withdrawn and re-laid in a more acceptable form or, if a negative, be revoked and remade. I wish to touch on one last issue: when it comes to the effective scrutiny of secondary legislation, it is crucial, as my hon. Friend the Member for Rhondda (Chris Bryant) has argued, that long-standing parliamentary conventions are adhered to. Even after the process of sifting undertaken by the new committee, SIs subject to the negative procedure can only be annulled if the Government of the day themselves allow time for the House to debate the matter and to have a vote on it. Yet, as my hon. Friend pointed out today and on Second Reading, the Government have consistently refused in recent years to honour that convention, just as they no longer honour the convention that Opposition day motions are voted on. We have a very recent example that illustrates how this Government have used delegated powers not just to avoid parliamentary scrutiny, but to legislate in open defiance of the will of the House in relation to the matter of tuition fees. The original Act in question with regard to that matter allowed any statutory instrument raising the tuition fee limit to be annulled by either House, and assurances were given by Ministers in both the previous Labour Government and the coalition Government that any such SI would be taken on the Floor of the House. By contrast, this Government prevented any vote whatever on the matter, and then refused to accept the vote of the House against the regulations. When they tabled the regulations the day before the 2016 Christmas recess, the Opposition prayed against them on the first sitting day this year, but despite the conventions of the House, the Government dragged their feet for months until eventually conceding the point and scheduling a debate on 18 April. Then Parliament was dissolved for the election. After the election, the Government stalled and it was left to my hon. Friend the Member for Ashton-under-Lyne (Angela Rayner) to secure parliamentary time using Standing Order No. 24. Eventually, we had to provide Opposition time on an Opposition motion to revoke the regulations, which the House agreed, only for the Government to refuse to accept the result, after telling Government Members to boycott the vote. Therefore, when Ministers say that Parliament still has a meaningful say on delegated legislation, there is a catch-and it is a Catch-22. They can refuse time for a vote within the 40 days, then say that it is too late for any vote to count once the deadline has passed. This Bill includes powers that not only open up the very real possibility of substantive changes being made to policies in areas that were previously underpinned by EU law, but to amend primary legislation. If the Government are willing to ignore so flagrantly the conventions of this House when it comes to an issue as controversial and as important as university tuition fees, why on earth should this House assume that those conventions will be honoured when it comes to Brexit legislation?
