The current lockdown has been branded “too lax” by a member of the Scientific Advisory Group for Emergencies (Sage).
Prof Michie, who is part of Independent Sage, told Today: “It is definitely too lax, because if you think about it and compare ourselves with March, what do we have now?
“We have the winter season and the virus survives longer in the cold, plus people spend more time indoors and we know aerosol transmission, which happens indoors, is a very big source of transmission for this virus.
“And secondly, we have this new variant which is 50 to 70 percent more infectious.
“You put those two things together, alongside the NHS being in crisis, we should have a stricter rather than less strict lockdown than we had back in March.”
