The right hon. Gentleman does not need to explain Scottish National party policy to me. Perhaps if he listens, I can educate him. Scottish National party policy is for an independent Scotland to join NATO—everyone, including him, knows that that would be accepted, by the way—but on the contingency that Trident will be removed from Scotland’s waters. That does not prevent the United Kingdom from continuing to have a nuclear at-sea deterrent, although we think it should not and almost certainly would not.
