This is a good read from Louise Armitstead in the Telegraph. Check it out!
The article cites Goldman Sachs:
Kevin Daly, part of the investment bank’s economic team, has concluded that a British departure from the EU would result in a “loss/loss scenario” in which both the UK and the rest of the bloc would be damaged.
Most interestingly Daly concludes that the UK is unlikely to leave the EC because that would require a referendum; he argues that a pre-requisite for the referendum would be the Conservatives winning the next general election but that is discounted as he expects Labour to win.
Personally, with the stockmarket at a record high in London, I think that Mr. Daly is probably right.
