My hon. Friend is absolutely right to raise the issue of security. It is one that is rarely raised in these debates. The majority of questions tend to be about the economic and trade relationship, but the security relationship is fundamental to us being able to keep ourselves safe. That is why I am pleased we have negotiated, in the political declaration, the strongest possible security relationship with the EU for the future of any country that would be outside the European Union. Of course, if we were to leave with no deal, those security relationships would not be open to us. Could we negotiate some for the future? That is, of course, possible, but it would require further negotiation and at the point of leaving those security relationships would be stopped.
