A third national lockdown in England has been raised as a possibility in the wake of the easing of Christmas lockdown restrictions.
More than 38 million people in England will go into Tier 3 on Saturday with even tougher restrictions possible later this year.
Wales announced a third national lockdown earlier this week beginning on December 28.
Northern Ireland will impose a six-week lockdown starting on Boxing Day, despite allowing Christmas bubbles to continue until December 28.
Labour leader Sir Keir Starmer told reporters “nobody wants a third lockdown”, but added the tiered system is not working.
He said: “Whether the Prime Minister rules [national lockdown] out or not is not the central question.
“I think the central question, Prime Minister, is what are you doing now to prevent the chances of a third lockdown?”
