Mutant Covid strain now appearing ‘everywhere’ in UK amid calls for national lockdown

Sir Patrick Vallance gave the grim warning after more than 40 countries banned UK flights because of fears regarding the spread of the coronavirus variant.

The chief scientific adviser’s remarks followed London and parts of southern and eastern England being rushed into the new Tier 4 lockdown regime at the weekend after existing Tier 3 measures proved inadequate to control the spread of the more infectious variant.

Sir Patrick indicated a lockdown may be needed in wider areas of England, particularly as Christmas mixing may result in an increased spread of cases.

Scotland and Northern Ireland have already announced new lockdowns from Boxing Day while Wales’ tough restrictions will only be eased for Christmas Day before being reimposed.

Liberal Democrat leader Sir Ed Davey tweeted: “People will have watched the PMs press conference and be wondering whether in a few days’ time he will be forced to announce a national lockdown and admit Dover has descended into chaos.”

Sir Patrick’s stark warning came as:

– Boris Johnson spoke to French president Emmanuel Macron as lorries queued in Kent after Paris banned them from travelling across the Channel.

– More than 500,000 people have now received the first dose of a vaccine in the UK.

– The Prime Minister refused to guarantee that schools in England will reopen after Christmas, saying “we want, if we possibly can, to get schools back in a staggered way at the beginning of January” but “the commonsensical thing to do is to follow the path of the epidemic”.

After the Government moved to impose Tier 4 restrictions, France shut its border with the UK for 48 hours prompting delays for freight lorries heading across the Channel.

The M20 in Kent was closed on Monday night to allow for the implementation of Operation Brock – contingency measures which involve using a moveable barrier to keep traffic moving on the motorway whenever there is disruption at the Channel – as confusion surrounded how many lorries were impacted by the border shutdown.

Mr Johnson said at a Downing Street press briefing the number of lorries waiting on the M20 had been reduced from 500 to 170, but Highways England later said Kent Police had told them there were 900 lorries parked on the motorway as of 6pm on Monday.

Government sources told the PA news agency that discussions with the French Government were “ongoing” after the PM said on Monday evening the two countries were working “to unblock the flow of trade as fast as possible”.

The BBC reported plans to reopen the border will come into effect from Wednesday, citing French Europe Minister Clement Beaune.

At the Downing Street news conference Sir Patrick said: “The evidence on this virus is that it spreads easily, it’s more transmissible, we absolutely need to make sure we have 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 it’s likely, therefore, that measures will need to be increased in some places, in due course, not reduced.”

The New and Emerging Respiratory Virus Threats Advisory Group (Nervtag) met again on Monday to consider the new variant and said, while it does not appear to alter the course of the disease, it does spread more easily.

“That again reinforces the point that it’s important to get ahead of this and to make sure that the tiering system is adequate to stop things going, and not to watch it and react in retrospect,” Sir Patrick said.

Given the “inevitable mixing” over Christmas “I think there will be some increases in numbers over the next few weeks”, he added.
