I welcome what the Leader of the House has said, but surely it is implicit that as well as there being an affirmative resolution of the House of Commons to deploy troops, there needs after some years of deployment to be a reaffirmation of that decision by a vote in this House. And if we ever have to do this again, there needs to be an institutional mechanism by which this House has direct access to the security and intelligence services, because such information should not be given to us by Ministers.
