It is true to say that you cannot really make an argument that Bercow’s action is supported by precedent or the rules of the House. What matters is if they are supported by the one rule of British politics that does matter: do you have a majority in the House of Commons? If you have a majority in the House of Commons, it doesn’t matter if you are found to have misled MPs, provided that majority is willing to sustain you in office. It doesn’t matter if you are upending centuries of precedent, because the only precedent that matters in our constitution is that Parliament can do whatever it wants.
