As I have already said we will get a deal on trade in goods like machinery, steel, cars, food, clothes, agricultural produce, but we will NEVER get to keep the 'Euro' trading that is handled through London. We never were in the Euro but trading in Euro markets and currency dealing is overwhelmingly done on the London market. The Germans have been trying for years to grab it for themselves and their Frankfurt dealing center. Now they have it handed to them on a plate and they will not let us get a look in!
London 'Euro' trading is HUGE business, it accounts for up to 40% of our entire foreign trade earnings. The City bankers will not be happy to see the end of their multi million £ salaries and even higher bonuses! Nor will they be welcome in Frankfurt & Paris they have enough traders of their own!
