A Sage subcommittee warned today the new strain may be more easily spread among younger children.

Chief Scientific Adviser Sir Patrick Vallance said tonight that more measures may be needed to get a grip on the virus.

Sir Patrick warned of the new mutant strain ripping across the nation: "It's more transmissible, we've absolutely got to make sure we've got the right level of restrictions in place.

"I think it is likely that this will grow in numbers of the variant across the country, and I think its likely therefore that measures are going to need to be increased in some places, not reduced."

Cases in London have doubled in the last week alone, it was confirmed today.

Prime Minister Boris Johnson was unable to commit to all kids returning to school as planned in January.

Johnson would only say tonight that he wanted to get schools back "if we possibly can".

The PM told the nation tonight: "I think the most useful thing I can tell you at this stage is obviously if we possibly can get schools back in a staggered way at the beginning of January, the way that we have set out.

"But obviously, the commonsensical thing to do is follow the path of the epidemic as we showed last Saturday and keep things under constant review.

"It is very, very important to get kids and keep kids in education if we possibly can."

Boris faces a nightmare before Christmas today as:

• France shut the border with the UK - forcing lorries with goods to line up for hours on both sides
• It was feared food supplies may be affected within hours - with Sainsburys warning about fruit and veg supplies in the run up to Christmas
• Millions were stranded or unable to travel after a string of countries banned flights to the UK over the new coronavirus strain
• A third of the country was plunged into Tier 4 yesterday - effectively another lockdown - cancelling Christmas for thousands of families
• MPs demanded a vote be held as soon as possible
• More than £33 billion was wiped off the FTSE 100 within minutes of opening over the chaos this morning

The PM appeared this evening alongside Transport Secretary Grant Shapps, just days after his national address on Saturday.

News of the mutant strain - which Health Secretary Matt Hancock said was "out of control" - has spooked other nations, who have shut the borders with the UK today and cancelled flights.

Hancock caused further dismay yesterday, after he suggested Tier 4 rules could stay in place for months - until the vaccination is rolled out to the most vulnerable people.
