Net contributions of £8bn is but 'p issing in the wind'...Someone no longer supporting Bulgaria, Romania, Poland, Croatia, Hungary, Spain, Greece etc? I don't think for one minute a real Brexit will be allowed to happen but if it did and the UK stayed firm for a while the EU would collapse.
But many quitters for some reason want the EU to collapse.
Why would they care that an organisation that they want to leave collapses or not?
What the EU does after the UK leaves is it's own concern, and xenophobic quitters have no place in saying what should happen after the UK sets sail on the Brexitanic!
