I obviously respect all the brilliant civil servants who work for us. I used to work as a Foreign Office lawyer myself. I can say to the hon. Lady that I am surprised she would open up this question. As we go through the uncertainty of changing our relationship with the EU, we will make sure that there is maximum certainty for businesses as regards the UK internal market, and of course we will legislate to that effect. Ultimately, we will take every measure necessary to protect the integrity of the United Kingdom and to comply with and live up to the Good Friday agreement, ensuring that it is respected. I am surprised she is not supporting that.
