Boris Johnson was facing a mounting backlash over his new Covid tiers last night – as it emerged the whole of England could be placed into the top two levels of restrictions.
Ministers will decide tomorrow which areas of the country will be placed into each of the three tiers.
But Whitehall sources told the Mail that ‘very few’ parts of the country would be placed in Tier One – the only level in which indoor socialising with other households will be allowed.
One source said that at least 80 per cent of the country would be in the top two tiers when they come into force on December 2.
Another said it was ‘entirely possible that no one is in Tier One’ when the figures are analysed by Health Secretary Matt Hancock and the Chief Medical Officer Chris Whitty tomorrow.
East Sussex, Herefordshire and Milton Keynes were the local authorities in England that suffered the biggest spikes in coronavirus cases during the most recent week, making them among the most likely to enter Tier Three rules.
Public Health England statistics show infection rates — the number of new coronavirus cases per 100,000 people — shot up by at least 50 per cent in all three areas in the seven-day spell ending November 15.
Kent, parts of Essex and London also saw large rises.

Covid-19 cases have fallen across most of the North of England since lockdown was imposed, but they are rising in a corner of the South East. The percentage change is based on comparing data from the week ending November 15 to the week ending November 8. It comes as the Government prepares to unveil its tier system

Meanwhile, the areas that saw the greatest falls in cases were almost all in Tier Three in the North West, adding further evidence that the local lockdown system appears to work.
Warrington, Oldham, Wigan and Blackburn, all of which suffered huge numbers of infections during England’s second wave, saw declines of 30 per cent or more.
Downing Street declined to comment in detail ahead of tomorrow’s decision, but pointed out that the Prime Minister warned on Monday that ‘many more places will be in higher tiers than was previously the case.’
Critics have accused ministers of failing to be transparent about the precise criteria used to decide tier placings.
Downing Street said five key factors would be used: Covid cases across all ages; cases among over-60s; the rate at which cases are rising or falling; the number of positive tests per 100,000 people; and pressures on the local NHS.
But No10 has given no details on how indicators will be used – and economic factors won’t be taken into account.
Tory MPs last night warned that the PM could face a major Commons revolt next week if the new system of regional restrictions is seen to be ‘lockdown by another name’.
One rebel source said almost 100 Conservative MPs had raised concerns about the continuing damage to the economy from restrictions that are due to last until April.
Tory chief whip Mark Spencer is said to have been deluged with messages from MPs warning that he cannot count on their vote if their constituency is placed into one of the higher tiers.

Sir Graham Brady, chairman of the 1922 Committee of backbench Tory MPs, said he was likely to vote against the measures when they are brought to the Commons early next week.
And he warned that the new restrictions would be ‘extremely damaging’ to firms already struggling to deal with the impact of two lockdowns.
He added: ‘My concern is that huge numbers of businesses particularly, but not exclusively, in the hospitality sector have been losing money under Tier Two already, and there is a very tight limit to how much longer they can go on doing that without seeing even bigger levels of unemployment, and, particularly, youth unemployment coming towards us.’
Fellow Tory Sir Desmond Swayne said: ‘The mood music seems to suggest that everybody is going up one tier – it’s going to be worse than before. We will have gone from lockdown to lockdown by another name.’
Downing Street yesterday acknowledged that the new system of tiers is ‘tougher’ than the one that was in place in October.
The hospitality sector warned that the proposals were so restrictive that many firms would not survive, particularly if they lose their lucrative Christmas trade.
Tier One is the only level where people are able to meet with those from other households indoors.
In Tier Two, socialising among groups of up to six is allowed, but only outdoors. In the new restrictions, pubs and restaurants will only be allowed to serve alcohol to customers also buying a ‘substantial meal’.
In Tier Three, pubs and restaurants will have to close for everything except takeaways.
Nick Mackenzie, boss of Greene King, Britain’s biggest pub chain, said: ‘My concern is much of the country will be in Tier Two or Three and that will be devastating for the industry.’
And Wetherspoon chairman Tim Martin, who runs 875 pubs, said: ‘We will be in an effective lockdown in Tiers Two and Three, and will be unprofitable.’

While Emma McClarkin, chief executive of the British Beer and Pub Association, said: ‘It seems the Government has chosen to inflict unnecessary pain and irreversible damage on our sector without publishing evidence…’
Downing Street yesterday rejected suggestions that the new system would be another form of lockdown, pointing out that shops, gyms and hairdressers would all be able to reopen in all tiers. The PM’s spokesman said ministers had been clear that ‘given the need to suppress the virus, there will be more areas in higher tiers.’
Health Secretary Matt Hancock yesterday told MPs he was hopeful that the tier system, coupled with mass testing, would avoid the need for a third lockdown.
Mr Hancock said there would be a shift to an emphasis on ‘personal responsibility’ rather than social distancing restrictions after Easter once the vaccine has reached the most vulnerable.
