I think the hon. Gentleman has slightly anticipated what I was about to say. It is indeed good news that progress is being made in that regard, but there is not much time left between now and March 2019, and there are still a number of treaties to go.
Lords amendment 3 addresses what is perhaps the most central point of the whole exercise. If those treaties are not securely in place before the date of withdrawal, we must have mechanisms for extending the period of coverage of Euratom, as it were—which means not just an extension during the implementation period, but an extension in its own right—until they are in place. We were told earlier in the Bill’s passage that all this was unnecessary, because everything would be put in hand before March 2019, and we have discussed the progress that has been made, but we have heard nothing about a plan B to be deployed in the event of its not being concluded. It may be that all the treaties will be in place, and we heard today that one of the bilaterals had been signed with the United States, but there are three more to be signed with major civil nuclear countries, and there is also the voluntary arrangement to be established with the IAEA. The Lords amendment gives us that fall-back protection, and a clear route towards obtaining it.
