Brexit is in the best interests of both Britain and Europe

MY city career was wholly concerned with an issue that goes to the heart of the UK referendum campaign - sovereignty. I was exclusively involved with financial securities and related instruments, including weathering London's 1986 "Big Bang" liberalisation. By then, I had already spent six years developing and running the Liffe financial futures exchange.

I was initially an economist, later a bond salesman in the market for UK government bonds, known as gilts, because of their absolute, sovereign guarantee. London then was the only significant such financial market in Europe.

In the 30 years since Big Bang, the financial markets in Europe have shown they can make giant reforms. Unfortunately, we cannot say the same of the European Union (EU).
