There was a guy on Newsnight in Derby questioned about another referendum who said that he voted remain before but would definitely vote leave if there was such a referendum 'because of the way the EU has walked all over us." While that is a purely emotional response that does not have any bearing on our long term future, I suspect it could be common enough to result in another Leave vote. It would be very unwise of anyone to make assumptions about how th2 voting would go.
