When pressed on whether the UK could afford to be complacent in terms of its measures, Hayward said: "Well, we can't. We've got over 8,000 people in hospital with Covid, nearly a thousand of them on ventilators. We have, compared to Europe, far lower numbers of hospital beds available to put people in, so we are on a bit of a knife edge here with Covid.
"But when you add in all the other respiratory infections that come in the winter when we've got high levels of population mixing, when you add in that huge [NHS patient] backlog, the
NHS is already in serious trouble. So I think we do need to be prepared to take action."
