My hon. Friend makes my case for me. If she wanted the information about these matters to be put before a court for a judge to decide, she would support the idea that, in a small number of cases, closed material procedures are necessary. I am afraid that I must tell her that in some circumstances if the secrets we hold, the capabilities, the agents and the capacities we have were to be put in open court, the security of our nation would be threatened. If she does not accept
that—I genuinely say this with respect—she has no appreciation of the importance of those secrets to our national security.
