Justice and Security Bill [HL]

My Lords, for the purpose of closed material proceedings and what we are dealing with here, national security is the specific concept, although it is not defined in the Bill. As I indicated, the Green Paper suggested that it might go wider to include some of the matters that the noble Lord, Lord Pannick, raised, but we have quite clearly indicated that that will not be the case in matters of national security. I give way to my noble friend who I understand was a counsel in Pepper v Hart.
