I approach the Bill in exactly the same spirit as my right hon. and learned Friend the Member for Beaconsfield (Mr Grieve) made clear earlier in the debate. However much I think we have harmed ourselves with the decision to leave the European Union, we have to ensure that we deliver it in an orderly fashion. That is critical in the legal area and in the business area. The City of London is the financial hub of the whole of Europe, and we want it to stay that way, but it requires legal continuity and certainty to do so. Now, I accept that the Bill seeks to do this-I have no problem with the intentions behind the Bill-but it is worth stressing the importance of the sector and, therefore, the importance of the detail. Bear in mind that euro clearing involves transactions being processed every day through London to a value which exceeds our annual contribution to the European Union by a significant sum, and which significantly exceeds any likely divorce bill figure that has been bandied about. The fact is that we are the basis for the euro bond market and we clear a great deal of euro business, and that generates and supports thousands of jobs. Some 36% of the population of my constituency are employed in financial and professional services. I am not going to do anything that puts their jobs at risk or reduces their standard of living. Those who voted to leave did not vote to make us poorer for the sake of a bit of ideology. We now have to find a practical means forward to ensure that we have, as the chair of the City of London's policy and resources committee put it, an orderly Brexit as opposed to a disorderly one. Therefore, the test of the Bill's contents is whether they achieve the Bill's stated objective of trying to assist in that orderly Brexit and withdrawal. Well, it does up to a point, but my contention is that it only goes so far. There are number of areas where the Bill is lacking, which is why it needs improvement, and this set of amendments deals with precisely one of those areas. The incorporation of the acquis into UK domestic law is accepted all round as being necessary, but the debate has highlighted a number of significant areas where there is still uncertainty and where the current wording may not achieve its objective. I want to see a deal on the basis of the Florence speech. I hope that all Government Members will stand behind the Florence speech and will not attempt to rewrite it, refine it, add to it or subtract from it. If we do that constructively, we can make good progress. I am sure that the Ministers on the Treasury Bench wish to achieve that too-well, almost all of them. But to do that we must ensure that we give the courts and contracting parties the certainty that they need. My final example is that derivative contracts are generally written over a three to five-year period. Unless there is certainty as to the enforceability of those contracts, people will not contract with counterparties in the European Union. Crashing out without a deal would not give them that certainty any more than going on to WTO terms will give the financial services any certainty. It would not give the London legal services sector any certainty, doing nothing to address the establishment directive or the recognition of professional rights that currently enable British lawyers to gain and earn millions of pounds for this country annually in the work that they sell into the European Union. All those things need to be done. I doubt whether we could get the detail done by the end of March 2019, and that is why a significant and proper transition, in which we can work out the details, is absolutely necessary. Let us make sure, then, that we enable the Bill to achieve that through some additions and changes to what is in it.
