Sajid Javid’s resignation in the Commons just now was coldly brutal. He’s had some practice, which he acknowledged, given this is the second time he has resigned in protest from Boris Johnson’s government. The first personal statement he gave was critical, but this one was terminal. He said ‘treading the tightrope between loyalty and integrity has become impossible in recent months’ and that as Health Secretary he had repeatedly given Johnson the benefit of the doubt over partygate and other scandals.
