For nearly three hours Boris Johnson refused to look at his reflection in the mirror. To have done so would have been to glimpse at the truth.
It would have been to acknowledge his excuses were pitiful, his defence preposterous, his whole explanation for Partygate was built on the flimsiest of foundations.
Presented with evidence he had attended events that clearly broke the Covid guidance, he responded with snarls and indignation. Perhaps the least trustworthy person ever to hold the office of Prime Minister was affronted that anyone would question his honesty.
