I think there have been several times when he has allowed obvious lies to pass unchallenged. For example, he stayed quiet when Vallance told us all that we were four weeks behind Italy, when this was very clearly untrue at the time. He told us that large outdoor meetings would have negligible effect. He said it was fine to book holidays, because if everywhere had the virus equally, it would make no difference.
Yes, he is very reassuring. That's why they have him up there. Sadly, I think he has allowed his ambition to outstrip his integrity.
