The Health Secretary is to set out which tier each local authority in England will fall under after the end of the national lockdown.
Matt Hancock will make the announcement in Parliament on Thursday after the Government set out its Covid-19 “winter plan” earlier this week.
Each area will be placed into one of three tiers when lockdown ends on December 2 – but the system has been toughened from the previous regime, meaning more authorities will move into the higher tiers.
Areas which make progress in slowing the spread of the virus could still be moved down a tier before Christmas, however, with the first review of the allocations due to take place by December 16.
On Wednesday night reports suggested there would be few areas in England placed in Tier 1, while London was expected to go in Tier 2 along with the majority of the country.
Mr Hancock said: “Thanks to the hard work and sacrifice made by people up and down the country, we are able to move out of national lockdown and into more targeted local, tiered restrictions.
