"In his resignation speech, Boris Johnson showed no awareness of any personal failings that had led his party to turn on him. "When the herd moves, it moves," he complained, without apparent thought as to what might have provoked the herd into stampeding. He later complained the rules had been changed halfway through the relay race that the premiership had become. There had indeed been no rule against No 10 parties, but by the time they happened in lockdown it was against the law. There was no rule that a PM must resign if more than 50 of their ministers quit, but since being able to form a government that commands a Commons majority is the basis for being in power it should hardly need saying that these are circumstances that make resignation inevitable. Boris tried to break rules that no one had previously thought it necessary to state."
