Well, I have just given two examples regarding subsections (A3) and (A5) of my hon. Friend's amendment, but I would be happy to sit down with him and give some illustrative examples of how, in practical terms, I think that this is not actually the avenue or legal cul-de-sac that he wants to go down. If my hon. Friend will forgive me, I will now turn to some of the other amendments in order that I give them due consideration in this important debate. In particular, I want to turn to amendment 278 and linked amendments 279 to 284 concerning exit day, which are from the Leader of the Opposition and other hon. Members. The Prime Minister made it clear in her Florence speech that“The United Kingdom will cease to be a member of the European Union on 29 March 2019.â€It is clear that the UK will leave the EU at the end of the article 50 process-some of the suggestions around the caveat are wildly unrealistic. The Government have tabled an amendment to make sure the drafting of the Bill is crystal clear on this point and to give the country-businesses and citizens alike-additional certainty and a measure of finality on it. These amendments would replace that clarity and finality with uncertainty and confusion. They would alter the meaning of the term “exit dayâ€ in the Bill, but only for the purposes of the provisions of clause 6. For those purposes, but for those purposes alone, the UK would not leave the EU until the end of the transitional period. I am afraid that that would create damaging legal uncertainty, and the amendments are flawed. They would have the effect that, for the duration of any implementation period that might be agreed-and we hope one will be, sooner rather than later-all the important provisions on the interpretation of retained EU law set out in this clause could not apply; they could take effect, if I have understood correctly, only from the end of that period. Since we have not yet agreed an implementation period with our EU partners, the effect of the amendments would be to create an indefinite and indeterminate transitional period, which rather raises the question of whether the Labour party is really serious about facilitating the process of a smooth Brexit at all.
