European Union (Notification of Withdrawal) Bill

My Lords, we have heard much about the issue of EU nationals being a priority, but, as the noble Baroness, Lady Symons, pointed out, whatever the ambition of the Prime Minister and however great her negotiating skill is likely to be, the nature of EU negotiations is that nothing is agreed until everything is agreed. So having this as a priority will not, in itself, give EU nationals the security that they need. If the Government do not feel able to accept the amendment—and I suspect that they will not—could the Minister give further clarification not about some distant immigration Bill that will come after the great repeal Bill but about something in line with and in the spirit of Amendment 9B that will occur in the immediate aftermath of triggering Article 50?
