European Union (Withdrawal) Bill

Does the hon. Gentleman agree with my view that most people in this country do not understand the huge benefits of the customs union? Of course, a huge swathe of people have never had any experience of stuff being stopped in customs. I certainly remember those days because of my age. Has it been his experience that British businesses are in many ways even more concerned about the movement of goods and tariffs and not being in the customs union than the actual imposition of the tariffs themselves? Companies such as Rolls-Royce in neighbouring Derby hugely benefit from these large supply chains and they are really worried about our leaving the customs union.
