The SPI-M-O group – which advises the top scientists – warned last week that any gap in measures would lead to a jump in infections as people ‘go back to their “routine” networks’ after mixing with family over the festive period.
Britons from up to three different households will be allowed to mix indoors and stay overnight with each other between December 23 and 27.
But many scientists have warned this is likely to lead to an uptick in infections as close contact with those who are asymptomatic or in the early stages of infection leads to its spread.
They have pointed to the flu bump – which normally happens every year after people mix over the Christmas break.
It comes as a Government graph published today suggest areas were allocated to their tiers by comparing infection rates for the last two weeks.
The Public Health England graph reveals areas may need infection rates below 100 cases per 100,000 people for at least two weeks before they will be considered for Tier One – the least restrictive measure.
The R rate was also found to have dropped below one today, as the lockdown puts substantial curbs on people’s movements in the country.
Briton recorded 16,022 new coronavirus cases today, a drop of 20.9 per cent compared to the same time last week showing the second wave has peaked. The country also recorded 521 deaths, a 1.9 per cent rise on last Friday.

Just THREE local areas saw Covid rates rise last week
Only three local authorities in England saw their coronavirus infection rates rise last week, official data showed- even though 99 per cent of the country will be plunged into Tier Two or Three lockdowns next week.
And more than half – 97 out of 149 – saw their numbers of Covid cases plummet by at least 25 per cent, according to Public Health England’s weekly infection surveillance report.
Medway, East Sussex and Redbridge, in London, were the three authorities to see rises in Covid-19 infections, by 28.4 per cent, 5.2 per cent and 5 per cent, respectively, as lockdown restrictions entered their third week.
Department of Health officials claim the percentage change in Covid infection rates was used as a key criteria for determining the tiers, alongside pressure on the local NHS, total infection levels, cases in over 60s and proportion of tests that are positive for Covid-19.
But figures back up claims from furious MPs and some scientists that ministers – who have refused to reveal what the exact thresholds are for placing restrictions on certain areas – should have placed more local authorities into looser tiers because of rapidly tumbling infections.
Experts said they felt ministers had been ‘cautious’ in applying tiers because of an expected spike over Christmas but that, once the festive period was past, it was likely many areas would be moved to Tier Two.
It comes after the Housing Secretary Robert Jenrick suggested this morning that local authorities could be shifted down to Tier Two before Christmas, providing their case rates fell to low levels. And Boris Johnson today admitted the brutal new Tiers are ‘frustrating’ for low-infection areas – but refused to change course insisting the rules must be kept ‘simple’.
And showing the second coronavirus wave has already peaked, the Cambridge University academics behind the gloomy 4,000 deaths-a-day estimate that spooked ministers into imposing a second national lockdown in the first place have revised their model to say that cases across England started declining last month.
The notes on the Christmas relaxation in measures were published today by the Department of Health, but are dated November 18.
They read: ‘Substantial mixing of people over a short period of time, especially those who do not make contact regularly during a month, represents a significant risk for wide-spread transmission.
‘Other respiratory infections suggest that exposure of elder family members to respiratory disease is increased during a normal festive period.
‘The prevalence could easily double during a few days of festive season, with further increases as new infections go back to their “routine” networks.’
The Government is considering imposing a 25-day lockdown after Christmas, giving five days of restrictions for every one day of relaxation to head off any further rise.
A senior Government source said this was ‘not an exact figure’ and that the five-day restrictions would only be needed if the Reproduction Rate or R – the number of people an infected person passes the virus to – rises to two.
‘If R rose to 1.5 it would be about two to three days of restrictive measures to reverse,’ they said.
‘For comparison, R is believed to be one nationally. Christmas will be a spreading event.’
The Prime Minister said he shared the frustrations of those in the highest tiers
Public Health England revealed today a graph suggesting how tiers were allocated for different local authorities in England.
It shows that although most of the North of England and the Midlands are in Tier Three – with restaurants forced to go takeaway only – many areas are well on their way to loosening restrictions and entering the coveted Tier One.
Nottinghamshire and Warwickshire are already close to dropping into Tier Two thanks to falling infection rates.
And there were also rapid declines in South Yorkshire, Lancashire and Derbyshire which could stand them in good stead for the coming weeks.
The report reads: ‘This chart shows some decreases in weekly case rates in the North of England, and other areas where case rates are high but declining.
‘Continued improvement over the coming period may make these areas candidates for de-escalation in the New Year.’
SAGE today revealed the R rate has dropped for the third week in a row, and is now thought to be below one for the whole of the UK for the first time in three months.
A row broke out last night over the Government’s tiering decision as MPs and members of the public in Tier Three areas were left in outrage.
They included the entirety of Kent, which has shifted from Tier One before the lockdown to Tier Three in response to surging local infections.
Damian Green, MP for Ashford in the county, warned he was ‘highly concerned’ about the dramatic downgrade yesterday and said ministers should publish detailed analysis on how their decision was made.
But Boris Johnson today refused to bow to pressure from 70 of his own MPs to change course, despite admitting they were ‘frustrating’ for people in areas with low transmission rates.
Speaking at the Porton Down laboratory site, the Prime Minister held out the prospect that some areas could see their status downgraded within weeks.
Mr Johnson said: ‘I know it is frustrating for people when they are in a high tier area when there is very little incidence in their village or their area. I totally understand why people feel frustrated.’
He added: ‘There really is the prospect of areas being able… to move down the tiering scale.’
Professor Paul Hunter, an infectious diseases expert at the University of East Anglia, told MailOnline today he felt the Government had been ‘cautious’ in applying the tiers due to an expected pre-Christmas surge in infections.
But he said that after the festive period many areas may be moved down the tiers.
The Department of Health today announced the new lockdown tiers that England will be divided into when the national lockdown ends on December 2
