For some this may look like a bad day for the UK but it's far worse for the EU. Belgium, France, Denmark, Italy, Holland and Sweden have all come out either saying they want out or have reaffirmed their stance on wanting out. Iceland have said it makes them less likely to join (didn't want to anyway tbf). In 10 years the EU could well be dead in the water anyway.
As for the markets pretty much every major one is in the red atm. The only one that has gained is gold. Also it should be noted I got 1.12€ to the pound last week after getting 1.24 the week before. It dropped from 1.30 to 1.20 around 2 this morning but has now bounced between 1.24 and 1.25 for the last hour or so. What's happening here is having an equal effect on what's happening almost everywhere else.
Now Cameron has gone Osbourne and to a lesser extent Corbyn has to go too now surely?
