Liz Truss today signed her own death warrant. Any hope she might have harboured of being able to ride out a disaster of her own making vanished during a nine-minute press conference.

It was not just having to U-turn on her signature policy of corporation tax cuts that sealed her fate. It was her complete inability to show any contrition for the damage she has inflicted on her country and her party.
