We have disagreed on many things over the years, but the Prime Minister knows that I have long respected her resilience, commitment to public duty and seriousness, as well as her work on national security. I assure her that there is much to be done from the Back Benches. She knows that I once said to her that I believed she was not the kind of person who would take this country into a chaotic no-deal scenario, not least because of the advice she had had on the risks to our national security. I am fearful about her successor, so can she reassure me that she really thinks, in her heart, that her successor will take those national security warnings as seriously as she has? If he does not, in October, will she speak out?
