It is a pleasure to follow the right hon. Member for Chesham and Amersham (Mrs Gillan), who has made some thoughtful and sensible points on her amendments, which we would support. I rise to speak to amendment 278, and to the consequential amendments 279 to 284, which would allow for transitional arrangements within the existing structure, rules and regulations. I will also speak to our amendment 306, but I will return to those separate issues later. Amendment 278 follows on from our earlier debate on clause 1. It brings into even sharper focus the issue of the Court of Justice of the European Union's jurisdiction during a transitional period. As I said in the previous debate, and as my hon. Friend the Member for Nottingham East (Mr Leslie) said earlier in this one, there can be no transitional period on current terms, as the Prime Minister wishes, without that jurisdiction. The Florence speech has been much quoted already, and I am sure that that will continue. Let me refer briefly to it one more time. The Prime Minister obviously made the speech after the Bill had been published, but perhaps its early drafting did not have the opportunity to accommodate the emphasis that she has placed on the“two important steps, which have added a new impetusâ€to the process. She said of the second of those steps:“I proposed a time-limited implementation period based on current terms, which is in the interest of both the UK and the EU.â€She was accepting the case made by business and trade unions for an effective transitional period and, crucially, again making the point that this should be on current terms. As I said in the earlier debate, we were pleased that the Prime Minister had caught up with Labour on that position. However, seven weeks on from the Florence speech, the Government have failed to reflect the ambition that the Prime Minister had at that time in any of the amendments to the Bill. They came up with the bizarre amendments that we debated in relation to clause 1, but they failed to address that ambition, so we have helpfully stepped in to fill that gap with amendments 278 to 284. The amendments would mean that, in relation to the jurisdiction of the Court of Justice, exit day should come at the end of the transitional period. The reason is simple: without acceptance of the continuing role of the Court of Justice during the transition, the idea that the implementation period, based on current terms, could happen in the way that the Prime Minister described is frankly delusional.
