My hon. Friend has rightly raised the effective use of the Dublin regulation on a number of occasions. We want it to be strengthened further, which is why I made the comment earlier about ensuring that we fingerprint those who arrive within the EU. I have already dealt with how Border Force uses its resources. It is right that it should do that. We certainly remain focused on the clandestine threat as well as on other threats to the UK border and on how we use Border Force resources and technology to meet those threats.
