One final comment from me on the day.
I have been seeing an awful lot of this: "What happens next?"
The short answer is exactly the same as it was the day before the referendum and the same as it would be had the Brits voted to stay.
No one knows.
They spent centuries going it alone against Europe. The corporate knowledge on how to do that is still there. They won't have any insurmountable problems going it alone again.
There are other countries that are fed up with the balance of power flip flopping only between Germany and France, being dealt out of negotiations, being told who and how many immigrants they have to take, yada, yada, yada. If enough of these look at the UK and say 'Hey, it works!' the EU will be nothing but a very expensive, failed experiment when they all pull out.
Canada, the US, Europe (in general) and some other countries in the free world are getting sick of professional politicians. People have decided they want some miniscule control over their own lives and are starting to lash out at anything that even resembles government control. It's bad enough when they are your own elected people, but when it's someone in another country telling you what to do, it's getting intolerable for lots of people.
