the Queen is not off the hook, if shit hits the fan.
conservative party member will vote in the new party leader, but PM is still "chosen" by the Commons, as the current majority is not obliged to swear unfaltering allegiance to Bojo/Hunt. if the new PM cannot command the confidence of the House because a handful of Tory PM already deny it, QE2 is in dilemma. she may very well has to recall May as the last affirmed PM.
“One possible scenario is that a group of Conservative MPs is so concerned about the winning candidate that they declare their withdrawal of support immediately the result of the leadership contest is known – ie, before the new PM is appointed. This would pose a serious dilemma for the Queen and those advising her, because it would not be clear that the new Conservative leader could command confidence.”
Poor Liz !
