I welcome the Prime Minister’s statement and the progress that has been made, but will my right hon. Friend make it clear that throughout the tangle of these incredibly complex and difficult negotiations, security co-operation must remain a national priority, and will she confirm unequivocally that this will be the case?

I am very happy to give that reassurance to my right hon. Friend. I am pleased to say that we are making good progress in our discussions with the European Union on both internal and external security matters.
