The Government's 'back to work' message could soon be scrapped in the latest Tory U-turn as coronavirus cases surge, it has been reported.
For weeks Downing Street has been urging Brits to return to offices following the easing of restrictions in order to help boost retail economies.
But now Britain is facing down the barrel of a second wave during the winter months.
Boris Johnson is set to address the nation from 8pm on Tuesday, including outlining the new 10pm curfew rules for the hospitality sector.
The PM will also tell people to revert to home working as long as it doesn't detrimentally affect business, reports the Daily Telegraph.
The newspaper says Mr Johnson will, however, stop short of a two-week “circuit breaker” lockdown.
Asked if London office employees could be advised to work from home from some point next week, Health Secretary Matt Hancock told Times Radio on Monday: "Well, I wouldn't rule it out."
During his address, Mr Johnson is expected to reiterate messages about hand washing, mask wearing and social distancing amid the soaring infection rates.
As well as the curfew, the hospitality sector will be restricted by law to table service only from Thursday.
Mr Johnson will chair meetings of Cabinet and the Cobra emergency committee - including the leaders of Scotland, Wales and Northern Ireland - ahead of a live, televised address.
It comes after the UK's four chief medical officers recommended raising the Covid alert level from three to four - the second highest - indicating the "epidemic is in general circulation; transmission is high or rising exponentially".
And earlier on Monday, Sir Patrick Vallance - the chief scientific adviser - said the UK could see 50,000 Covid-19 cases a day by mid-October and a daily death toll of 200 or more a month later unless urgent action is taken.
A No 10 spokesperson said: “No-one underestimates the challenges the new measures will pose to many individuals and businesses. We know this won’t be easy, but we must take further action to control the resurgence in cases of the virus and protect the NHS.”
