The hon. Gentleman tempts me down an avenue that has nothing to do with the point I am making, which is that it remains unclear why the Government tabled three exit day amendments to their own Bill which have sown further confusion. We do not know why they did that—whether it was driven by Tory party management considerations or some other reason. The effect of those Government amendments would have been to end the jurisdiction of the ECJ on 29 March 2019, thereby preventing agreement on a transitional period on current terms.
The Government clearly soon realised their mistake and to save face enlisted the right hon. Member for West Dorset (Sir Oliver Letwin), who is not in his place, to table amendments to loosen the legislative straitjacket they themselves had created. But his amendments, which the Government have accepted, only provide a limited form of flexibility. Ministers may now amend the definition of exit day in clause 14 for the purposes of the Bill if the date when the treaties cease to apply to the UK is different from 29 March 2019. However, there is good reason to argue that that power might not be sufficient to facilitate transitional arrangements after 29 March 2019 on the same basic terms as now. If it is not—this might end up being the most bizarre aspect of the Bill’s curious parliamentary process—the Government will find themselves in the ludicrous position of having to amend this Bill when they bring forward the withdrawal agreement and implementation Bill later this year.
