Whether by accident or design (it looks like design), Amber Rudd has chosen to resign, not just from the cabinet, but from the Conservative party as a whole, with maximum brutality. Whereas Jo Johnson, Boris’s younger brother, chose to go quietly and with dignity (we should not forget that it was Jo who got the first class degree), Rudd has chosen to plunge the knife in by co-opting the Sunday Times. Presumably she, like so many One Nation tories, was persuaded to join the cabinet by the hope and promise of a deal, a promise which we have now all discovered was, as Cummings so delicately describes it, ‘a sham’. She was led down the garden path by continued promises and expectations of a better deal, now in ruins. No wonder she and her ilk are angry. Let’s hope that she will persuade more to join her.
