Ah I thought it was extension but from other comments it seems they can just cancel Article 50, my bad. That requirement for a second referendum might be a good thing though, seems like that's the only way out politically (to be forced by an outside force) given how many of the heads party have said a second referendum would tarnish the democratic process (which is BS to me but that's their stance).
