Trade Bill

My Lords, I will not go into the matter of the definite or the indefinite article, which I think is getting a little abstruse. The right reverend Prelate asked why there was a focus on the words “customs union”. It is because that is one of the two ways under article 24 of the World Trade Organization’s rules—a free trade area, or a customs union covering substantially all the trade—which permits a member of the WTO in good standing to derogate from the most favoured nation provisions. It is as simple as that. All that waffle in the political declaration, which had to be put in because “customs union” would have frightened too many horses, is quite meaningless. “Customs union” is totally meaningful.
