Corbyn, in particular, is trying to wreck the whole process. He is deluded that he will win any forthcoming general election, and has made that his goal, to the detriment of everything else.
Hardly. Just like all the Tories who might have callenged May for the leadership, he knows that he doesn't want to be responsible for the clusteropps that Cameron, May, parliament, the EU bureaucracy, both parties and the electorate have caused between them.
There is no way out of this that won't create a longlasting politcal problem.
Taking back control is a joke, our politicians have proved they couldn't control an unplugged kettle.
