Nobody is leaving the EU at present PI, deffo not the UK.
I wouldn't be so sure. I work in finance and even in our company there are some people who will be voting out. Even if they lose their jobs over it.
A lot of people are very determined to get out of the EU, NO MATTER THE COST.
The cost will be large. Overseas investors are very wary of putting money in the UK if it votes out. We have $400m waiting to be invested in the UK by US/EU investors. If we vote leave, half won't be coming here. Its a similar deal with commercial property, for instance, all recent deals have Brexit break clauses.
Our company is very small, this story will be reproduced all over the country. The figures could be huge, FDI in the UK varies between £25-80 billion per year. Those are jobs, tax income and public services that will disappear.
London is of course the EU headquarters for most international companies, many will have to relocate.
You may think, it won't matter if you don't get directly affected, well it will. Unemployed people don't pay tax and they cost money that the remaining works have to makeup.
I have a colleague who hangs about with Conservative MP's. He's hoping they can destroy the Welfare state once free of the EU and the public put the extreme right of the Conservatives in power with this vote.
