Doesn't work Mr McGrath, Steve reckons we need a 60% majority to remain in order to reverse the result?
Additionally after "best of three" it would become "best of five", Seven, Nine.   A referendum is what it says on the tin...a one off for better or worse.
When it came down to the wire, the UK public voted out and out we must go.    A bit of unity in negotiation and less carping by the remainers would assist our cause, anyone would think you people actually want the country to fail?
Get behind the Brexit team and get the best deal possible....if that turns out to be impossible through EU intransigence, we can do it easily on our own.
