Also worth noting regarding whoever the Tories elect as leader... The Cabinet Manual says that once a PM resigns ''The Sovereign will invite the person who appears most likely to be able to command the confidence of the House to serve as PM'' If that is a hard Brexiter, especially a No Deal one like Johnson, then I can think of a few Tories who won't support such a person. With such a slim majority in the HoC, it looks like what has dogged Brexit all along will also be a problem with whoever they elect, in that if you appease one side of the Brexit divide you alienate the other side. And if Johnson wins and calls an election, he's skating on thin ice, at the last election his majority was halved down to 5k, throw in a rejuvenated Lib Dem party and the Brexit party and that could disappear very quickly. More fun and games ahead people...:)
