I agree. Other states have an opportunity to agree a deal, because it would be obtainable under qualified majority voting, and does not require unanimity, as a careful look at article 50 shows, although that point was not initially understood.
If the UK leaves the customs union, a huge amount of work will be required to develop and enforce rules of origin. Despite the extra bureaucracy, I still think there is merit in leaving. If the greatest opportunities turn out to be in Asia in the medium to long term, as many forecast, we should put the country in a position to benefit. I strongly agree with my hon. Friend the Member for Gainsborough (Sir Edward Leigh), who is no longer in his place, that a liberal economic internationalism should underpin everything we try to develop in our trade relations.
