As I think I made clear, in the event of a deal during the transition period we revert to the old 2008 regulations and they remain in effect for the implementation period. Thereafter, it depends on the outcome of the negotiations.
I come to the point raised by the noble Lord, Lord Redesdale, about the cost of some new IT system. All I can say at the moment is that no bespoke IT system is required as a result of the procedures set out in these regulations. The cost relates to administrative working hours.
Finally, I notice the point made by my noble friend Lord Selborne and the noble Lord, Lord Grantchester, about Euratom. We will leave Euratom; that has been made clear and is cut and dried. But obviously we will continue to work with it, as we have made clear on a
number of occasions—not least during the passage of the then Nuclear Safeguards Bill, which now seems an awfully long time ago.
