Bercow should be totally non biased, he should be 'playing blinders '
As for the referendum being advisory, that's as may be, so why didn't MP's refuse that advice?!! In signing article 50, they not only agreed the advice, but potentially voted for no deal, so they can hardly complain when faced with what they themselves put into law, why on earth do that in the first place? Perhaps they didn't understand what they were voting for?! If they didn't, how earth do they suppose that we do? and if they think we don't, then why ask in the first place. What complete fools they all are!
