Anyway, I think it's looking more and more hopeful that there can be a second referendum. There's a hell of a lot of precedent, things are going extremely wrong from the go, some politicians are starting to give lip service to the idea and in Farage's sentiment, the narrow margin suggests that this is unresolved. Leave has the democratic mandate right now, but with a "material change in circumstances" (i.e. a big swing in public sentiment), a new democratic mandate may need to be sought.
