Northern Ireland (Executive Formation) Bill

The hon. Gentleman is being very generous in giving way. He says that he can remember the time when gates were left open and animals wandered across the border. He suggests that we would have to avoid that. I am intrigued by this. For the life of me, I cannot understand how he believes that the EU Commission, with all its powers, is going to be able to instruct cows not to wander across the border and not to find holes in hedges, gates that have been left open or lanes that have been left unpatrolled. Could he please tell us how this will work, because I am intrigued?
