European Union (Notification of Withdrawal) Bill

My right hon. Friend is a man of courage with a long, fine history of supporting the sovereignty of this place. He says that the Government will give us a vote in the event of a deal, but why does he not agree with those of us, on both sides of the House, who want the same vote, so that we ensure the sovereignty of this place, in the event that the Government cannot strike a deal, despite their finest efforts?
