Enough is enough. The City of London is Britain’s most important industry and we can no longer allow the European Union to trample all over it. Over the past few years, we have all too often turned a blind eye to the EU’s increasingly vexatious attacks on financial firms, largely because few politicians had the self-confidence to be seen to be taking the side of bankers. But with the Brussels machine now gearing up for an intensification of the hostilities, it is time for the British Government to become much more forceful in its defence of our economic interests.
