I thank my hon. Friend for his intervention. I do not have that detailed knowledge, but I am aware from talking to people who work in the NHS that there is a great deal of concern about that situation.
Many European Union citizens have left the UK, and it cannot be right for them to be so worried that they will be unwelcome that they leave, rather than risk staying. The Government have said that European Union citizens living lawfully in the UK today will be able to stay, but they will need to register for settled status under
a new scheme, which is not yet up and running. That is not what those people signed up for, and they are understandably worried about a new regulatory framework replacing what was free movement between the UK and other European Union countries. Of course, that works both ways.
I do not speak as a technical expert on the mechanics of Brexit, and I do not suppose that Ciaran is a technical expert either. However, he and over 110,000 petitioners—a number that was still growing as of yesterday evening—say that they have huge concerns about the impact of Brexit on the areas I have mentioned, and that if there is no deal, or a deal that cannot deliver assurances on all of those issues, Brexit should be stopped.
