My Lords, I fully support my noble friend’s decision to raise these questions, which are very important. I suspect the Minister will say that the Government have given a commitment that, when the withdrawal agreement is concluded, it will become before this House an Act of Parliament and we will therefore have the opportunity to debate it then. However, there are two powerful reasons why citizens’ rights should be incorporated in this Bill now.
The first is the high level of anxiety that EU citizens have about their position. I am sure there is relief that, in principle, an agreement was reached in December, but there could still be many a slip between cup and lip in its ratification. Those citizens’ rights should be guaranteed now to provide reassurance.
Secondly, I listened hard to an earlier contribution from the noble and learned Lord, Lord Brown of Eaton-under-Heywood, in which he said that the main utility of this Bill is to make sure there is legal certainty if we crash out of the EU— because, assuming that negotiations work, there will be a transition period during which EU citizens’ rights will not be affected. The problem we are dealing with particularly in this Bill is the risk of a crash-out. Of course, the Government will say to us, “Well, we’re very determined there won’t be a crash-out”, but they will not exclude that possibility. It was clear from the intervention at the end of my noble friend Lord Foulkes’ speech that the noble Lord, Lord Forsyth, actually relishes the possibility of a crash-out because he thinks, wrongly, that this is some bargaining leverage we have over the EU.
