Despite the fact that I think #DominicCummings is dangerous (because of his arrogance), he is an advisor – not a politician. He has never stood for office, nor put himself up as a particularly worthy person. Thus he should not resign on this kind of matter. He is responsible for his advice and nothing else. Giving bad advice or lying to his boss is another matter. We need to clarify, not blur the advice/decision-maker boundry.
