There are certain manufactured goods where they have that, but across the piece of a whole economy we do not see a circumstance where rules of origin have been abolished in the way the hon. Gentleman describes. Rules of origin are really quite burdensome for manufacturers to prove. They have to count the content and document where components come from. They then have to lodge those documents as they cross the border. My point is that the facilitated customs arrangement, with its rules of origin requirements, will have friction at the border. For that reason, we are going to have to accept that a customs union is preferable.
