On a personal level, I am deeply sorry for Boris Johnson and his family. Being in intensive care is no joke, and with the virus, nobody really knows what to expect. I wish him and his family well.
That having been said, Raab, the 3-Minute-Wonder, is not a fit and proper person to charge with prime ministerial duties. Whatever the Tory press, and failed former ministers, Iain Duncan-Nip-Off-Smith and the like, may say, he has not the experience, and he has not the judgement.
