Boris Johnson has announced new Covid restrictions in England amid concerns about the spread of the Omicron variant.
Speaking at a Downing Street press conference on Wednesday evening, the prime minister said people should once again work from home where possible from Monday.
Johnson also said vaccine passports will be required for some venues including nightclubs.
Mandatory mask wearing will be expanded from Friday to “most public indoor venues”.
The tightening of the rules comes amid widespread anger about accusations that No.10 staff held a Christmas party last year that broke lockdown rules.
