Given that Labour party policy on a second referendum was different a week ago from what it is today, may I encourage the right hon. and learned Gentleman to be more optimistic? The Prime Minister could indeed get changes to the backstop—a time limit, or a get-out clause for later on. If she does make those changes—if she is successful—given what the right hon. and learned Gentleman has just said, will he then support the Government in order that we avoid no deal?
