I have had conversations with a number of my trade colleagues from Japan, Mexico and Canada all ahead of the G20 meeting. That is a very good opportunity for us to recommit ourselves to the concept and practice of free and open trade and the rules-based system based on the WTO in Geneva. We should be pointing out that protectionism has never ended well, and that the benefits that we have introduced in terms of the elimination of poverty and the support for our global security agenda are based on free trade. It is also worth saying that the alternative to a rules-based system is a deals-based system, which would upset the balance of global trade. Incidentally, let me point out to the hon. Gentleman that he will find that the power to withdraw from the WTO is not a presidential power, but one that would require approval by Congress in law.
