Dominic Cummings is an arrogant, aloof, pretentious, self-aggrandising, domineering, vain and thuggish zealot who will listen to nobody.
That is the profile that has made itself apparent to Nick Cohen. There are two other qualities I could add to that list but I must give way to diplomacy. Yet apparently it is we who are uncooperative. Funny that.
Answering Mr Cohen's question as the whether the man has sabotaged the ant-EU cause, I speak for a fair few when I say unequivocally, yes, he very much has.
