When Boris Johnson was asked at today’s Covid press conference whether he could rule out an imminent cabinet reshuffle, he didn’t give anything away. The Prime Minister joked that it was a question for the chief medical officer before avoiding offering an answer himself. While Johnson may take the view that the focus on a reshuffle was a distraction from his Covid winter plan announcement, it’s also the case that the constant rumours are starting to become a serious distraction for ministers, aides and civil servants.
