England could be heading for a new nationwide lockdown after Boxing Day, with many areas at risk of being plunged into Tier 4.
The government held a "Gold Command" meeting on Tuesday to discuss putting Birmingham into Tier 4 before Christmas, reports Mirror Online.
The Mirror also reports that some officials called for the whole of England to enter the toughest tier of restrictions from Boxing Day.
One source in the meeting said: “The situation is developing quickly so we need to respond at the same pace.
"It’s more likely that other parts of England could be put into Tier 4 from Boxing Day”.
Reports suggested ministers would meet on Wednesday to decide whether more parts of the country would be put under the toughest restrictions amid fears over the spread of a new mutant strain of coronavirus.
It came as France lifted its travel ban and allowed journeys from the UK to resume, but said those seeking to travel must have a negative coronavirus test result.
The Daily Telegraph reported local leaders and health officials in Birmingham met on Tuesday night to discuss the possibility of the city being moved into Tier 4, while areas in lower tiers could be moved up to Tier 3.
Genomic researchers have found the new variant, which is said to be 70% more infectious than previous strains , has already spread around the UK, with cases identified in Wales and Scotland.
Health chiefs in Cumbria have said the new variant is in the county and could be behind sharp increases in new cases, while Lancashire's director of public health said there was a "high likelihood" the new variant was in the county.
Labour leader Sir Keir Starmer has written to the Prime Minister to say his party would back any Government moves to tighten restrictions if that is what scientists recommended.
Sinn Fein has said an island-wide travel shutout should be introduced in Ireland to stem the spread of the new variant there.
Meanwhile, it is expected NHS Test and Trace staff and the military will be deployed for the mass testing programme in Kent, where more than 2,800 HGVs were stuck on Tuesday afternoon.
France said a negative test result taken less than 72 hours before the journey would be required for those entering the country from the UK.

Transport Secretary Grant Shapps said rapid lateral flow tests - which can give results in about 30 minutes - will be used in the testing programme, while the French authorities will be carrying out similar testing on hauliers entering the UK.
Full details of the testing programme have not yet been released, but Mr Shapps warned it could take until Christmas for congestion to be relieved near ports.
He said: "We have managed to get all those tests to Kent, enough for all the vehicles which will want to return before Christmas, so that won't be an issue.
"Obviously there's a physical issue of providing the test, getting the results. A negative test allows you to leave.
"But all of that requires operationalising and that can't happen in an instant, so this will take two or three days for things to be cleared."
He urged hauliers not to travel to Kent until further notice.
