I think these exchanges are proving of use to the many people who will look at them in Hansard tomorrow and in the weeks to come. We are in  an increasingly global economy. Many workers can expect to spend part of their careers working elsewhere, and there are many foreign workers coming in and out of this country. These are the sorts of practical issues we need to be quite clear about in order to give guidance to employers and employees alike as to what the new regime is likely to allow and not allow. Having  heard the Minister’s reasonable explanation, I beg to ask leave to withdraw the amendment.
