Lie (Dec 1): "All the guidelines were observed." Plainly not true.
Misleading and pathetic (Dec 8): "I have been repeatedly assured that the rules were not broken." Misleading because it implies he wasn't there when he was - one might reasonably expect the Prime Minister of the country to not need somebody else to assure him if he was actually there. Pathetic because this is indeed what he's claiming - despite being PM, a position that demands considerable good judgement, that he himself is not capable of judging a breach of the very rules that his government put in place.
Boris is not a leader. He tries to hide behind lawyers' language, but that's still misleading and he left it a week too late. He is so far from the best that we could have. This much has been known by many in his own party since long before he was elected. He should resign for misleading Parliament, that's a resignation offence. He should resign for being the first sitting Prime Minister in history to have been found guilty of breaking the law (his own law!). And if he doesn't resign for one of those two reasons then Tory MPs need to relieve him of his position, or they're all as culpable as he is.
