Snarls and smears from disgraced Boris Johnson, readying his troops for civil war | Polly Toynbee

The Partygate report could not be more damning - but his only concern is for those who still mass under his tattered flag

Ninety days' suspension and a lifelong ban from a pass to enter the Palace of Westminster. This is the punishing verdict for the only prime minister ever found to have misled parliament. Naturally, Boris Johnson lashes out at the privileges committee judgment as a final knife-thrust in a protracted political assassination", designed to find me guilty, regardless of the facts". All the committee's painstakingly careful yet eye-popping evidence bounces off him, as he treats the detailed accounts of six (plus another 16) Downing Street parties, and the lies he told, with total contempt. Furious self-pity, paranoid victimhood and faith in his golden merit is true to form.

This verdict should be the stake through the heart of a disgraced career. Anthony Seldon and Raymond Newell already produced enough devastating evidence in the biography Johnson at 10 to prevent any conceivable resurrection of this monster, you would think. At a literary event this week, Seldon signed my copy with: A story about the worst prime minister in (modern) history - rotten to the core."
