There have been more than 1.5 million confirmed cases of coronavirus in the UK and more than 55,000 people have died, government figures show.
However, these figures include only people who have died within 28 days of testing positive for coronavirus and other measures suggest the number of deaths is higher.
The government said the restrictions will be tighter than they were in the pre-November tier system, and areas will not find out which tier they are in until Thursday.
Rates of cases
The rate of cases of Covid-19 in Luton was just below 300 cases per 100,000 people in the week to 20 November - the highest in the Eastern region.
While many districts have seen a fall in the week-on-week rate, Luton has seen a rise and has the 66th highest rate in England.
Lucy Hubber, interim head of public health for Luton, said lockdown had "not had the impact we hoped for".
She said the high rate of cases meant residents will "have to make more sacrifices coming out of lockdown".
South Northamptonshire and Northampton have rates above the England-wide average, but both have fallen week on week.
Milton Keynes has seen a slight rise in cases week on week, the only district in Buckinghamshire to do so.
All districts in Hertfordshire, except Dacorum, have seen their rates fall.
In Cambridgeshire, East Cambs was the only district to see a week-on-week rise.
