It may not be this week. It may not be Boris Johnson. But eventually a minister will break with this tottering government and establish himself (or herself, for it could be Andrea Leadsom) as the leader of the diehard right. Brexit is crying out for its Ludendorff; the scoundrel who can blame his failures on everyone but himself. The smart move for today’s right wing politicians who find their careers blocked is to break with the Tory leadership – whatever or whoever that may consist of – and resort to old slogans.
