Behind the crumpled shirts, tracksuit bottoms and “critics go hang” persona of Dominic Cummings lies a man who really does care what people think of him. And most of all he wants to be seen as a winner. Having been given huge credit – and even a Benedict Cumberbatch docu-drama – for his part in making Brexit happen, he desperately wanted to be The Man Who Beat Covid. The fact that he failed in that mission, whether through his own inadequacies or, as he believes, because people in power didn’t do as he said, has been eating away at him ever since he was forced out of Number 10 last November. The one person he is never likely to blame is himself. Imbued with the self-belief of a cult leader, Mr Cummings must instead find others to shoulder the blame, regardless of whether the facts get in the way of his narrative. Mr Cummings’s new-found zeal for public scrutiny is particularly hard to fathom. In a 26-part Twitter thread on Tuesday, he insisted that “one of the most fundamental and unarguable lessons of Feb-March is that secrecy contributed greatly to the catastrophe. Openness to scrutiny wd have exposed Gvt errors weeks earlier than happened”.
