Restrictions will have to be tightened after Christmas, a Sage scientist has warned, as Britain prepares to form bubbles for the festive period.
Professor John Edmunds, a member of the Sage scientific advisory panel, said the tier system is not “holding the epidemic wave back”.
“I think we are going to have to look at these measures and perhaps tighten them up, we really will,” he said.
“It’s a horrible thing to have to say but we are in quite a difficult position.”
However, Prof Edmunds, of the London School of Hygiene and Tropical Medicine, said the relaxation of restrictions at Christmas is “probably not good for the epidemic”, it is “probably good for people’s wellbeing in other ways”.
Schools minister, Nick Gibb, has said another national lockdown could not be ruled out.
