This map shows how England's tiers for coronavirus will look from Boxing Day.
Earlier at a Downing Street press conference, Health Secretary Matt Hancock announced changes to the tiering system which will come into effect at one minute past midnight on December 26.
Millions more people across the south east and east of England are to be moved into the toughest Tier 4 restrictions from Boxing Day as the number of Covid-19 cases spread.
Mr Hancock has also said that two cases of another new strain of Covid-19 linked to South Africa have been identified in the UK.
More detail was given at the briefing on the current situation with the coronavirus pandemic.
The areas that are being moved to Tier 4 are: Sussex, Oxfordshire, Suffolk, Norfolk and Cambridgeshire, those parts of Essex not yet in Tier 4, Waverley in Surrey and Hampshire including Portsmouth and Southampton but with the exception of the New Forest.
Bristol, Gloucestershire, Somerset including the North Somerset council area, Swindon, the Isle of Wight, the New Forest and Northamptonshire plus Cheshire and Warrington are moving up to Tier 3.
Cornwall and Herefordshire which have seen “sharply rising rates” are moving up to Tier 2, Mr Hancock announced.
All the new measures are being imposed against a backdrop of increasing infections, hospital admissions and a new more contagious variant in the UK which was announced on Friday.
Mr Hancock said Covid-19 is spreading at a “dangerous rate” across large parts of England and it is “better to act sooner”.
Mr Hancock said that Tier 3 “is not enough to control the new variant” and the number of cases have been rising in areas which are near to sites which are already in Tier 4 restrictions.
More of the East and South East of England are going into Tier 4 as East Anglia has seen “a significant number of the new variant and we’ve seen case rates rise sharply”, Mr Hancock said.
There are also “some early signs” of the new variant and rising cases in the South West which also now faces tougher restrictions.
