And whilst people think Swiss bank accounts are the worst in terms of hiding dirty money, the nebulous network of tax havens based on Crown dependencies and "British" Commonwealth nations is unrivalled.
Unlike the Germans, Japanese and US Americans, the Brits don't need an orderly, streamlined and legally coherent system. The Brits thrive on a byzantine, global, murky banking prison colony. They are inmates who somehow were entrusted with the keys.
