I am grateful to my hon. Friend for returning the favour. Does despair, like me, when confronted with arguments to the effect that we can somehow return to a Bretton Woods system which depended on one major currency instead of several as we have now, and which existed when there were capital controls on all the major economies, so that there were no international capital flows such as we have now? Does he not despair when people simply ignore the fact that even a big currency like the yen can crash and be subject to speculation? Labour Members seem incapable of learning that even the euro, stretching across an entire continent, could be speculated against, be unstable and lead to economic dislocation within that area.
