Brexit could be the makings of a Corbyn primed to lead nation

It is an extraordinary comment on the Conservative Party that they have made Jeremy Corbyn electable.

The horror of that spectre, together with a residual but no longer fully functioning appetite for power, is what keeps it together. Laying down her Brexit plan at Chequers last week, Theresa May, like John Major on June 22, 1995, challenged her critics to put up or shut up.

A formal leadership challenge may come, but it was the moment she turned around to face down her critics within.
