European Union (Notification of Withdrawal) Bill

My hon. and learned Friend is right to point out that progress has been made, but does he agree that to make a vote at the end of the process meaningful, we have to have meaningful scrutiny as the process goes on, and as a Parliament we have to have the chance to say to the Government, “You must go back and try to do better”? Having an all-or-nothing vote at the end, when all the discussions and negotiations are over, is not, in my definition, meaningful scrutiny. Does he agree?
