I want the deal to be done and the security argument is an important one. When my right hon. Friend the Minister for Europe was answering questions yesterday, he was asked whether it is consistent to say, as we do in the document, that national security is a national competence and to argue that Europe is important for security. I believe that it is. It is very important that we are clear that the core competences such as policing and our intelligence services are for this House and our Government to decide on, but of course there are ways in which we can co-operate in Europe to make ourselves safer, such as making sure that we know when criminals are crossing borders and making sure that we exchange passenger name records and the rest to keep us safe. That is why, when we opted out of the justice and home affairs powers, repatriating about 100 powers to Britain, we stayed in the ones that really matter in respect of keeping us safe. It is important to demonstrate that we are both maintaining national security as a national competence and working with our partners to keep our people safe.
