To be frank, I was not being careful with my terminology. If the hon. Gentleman is asking, “Is there no infrastructure?”, there is no infrastructure. In relation to cameras, I saw cameras in Northern Ireland on the main road. I do not think it would be tenable to have cameras all along the border. They would simply be ripped down and be targets for terrorists to attack. I think he has successfully stretched my desire not to comment in any more detail. Certainly, he has done so effectively.
