My main point was people who lead the government both PM and a majority in the cabinet should actually believe in a course of action to have any chance of delivering it succesfully. It would also mean Brexiteers in government having campaigned for it would be entirely responsible for delivering on promises made.
But, as I pointed out yesterday (and you totally ignored), you make it sound like some sort of establishment plot. The Tory party membership is overwhemingly pro-Brexit and would easily have voted in a Brexiteer. It didn't because none wished to go forward to a ballot of members. Johnson would have won easily if he'd stood, as would Leadsom ... but they didn't wish to.
May has been careful to ensure that the cabinet is equally divided between Remainers and Brexiteers and the key Brexit jobs have all gone to Leavers. So to say that "both PM and a majority in the cabinet should actually believe in a course of action to have any chance of delivering it succesfully" is just total nonsense.
