British prime minister Boris Johnson imposed tougher Covid-19 restrictions in England on Wednesday, ordering people to work from home, wear masks in public places and use vaccine passes to slow the spread of the Omicron coronavirus variant.
Undermined by accusations that his staff partied at Downing Street during a Christmas lockdown last year, Johnson said Omicron was spreading rapidly and he had no choice but to move to "Plan B" while a vaccine booster programme rolls out.
While still a long way from the full lockdowns imposed earlier in the pandemic, the new measures were described as a "hammer blow" for city centre restaurants, cafes and shops that are desperate for Christmas trade to rebuild their finances.
Many lawmakers in Johnson's own party are also angry with the new restrictions, fearing the impact they will have after the economy shrank by a historic 10 per cent last year.
"While the picture may get better, and I sincerely hope that it will, we know that the remorseless logic of exponential growth could lead to a big rise in hospitalisations and therefore, sadly, in deaths," Johnson told a news conference.
Sterling fell sharply when news first emerged on Wednesday that 'plan B' measures were imminent and investors pared back their bets on a Bank of England interest rate hike next week.
Johnson, who lifted most Covid restrictions in England in July following a rapid vaccine rollout, had vowed to navigate the winter without resorting to a fourth Covid-19 lockdown, but had kept a so-called Plan B in reserve.
Part of those measures, such as reintroducing masks on public transport and in shops, had already been brought in, but on Wednesday Johnson said people should also now work from home.
Face masks will be required in public venues such as theatres and cinemas and a Covid pass will be mandatory for access to nightclubs and venues with large crowds.
Johnson said the new measures were needed after 568 cases of Omicron were found in the country, with data suggesting its doubling time of infections could be between two and three days.
England's health minister Sajid Javid said officials estimated that the number of Omicron infections was actually around 20 times higher than the number of confirmed cases, meaning they could be closer to 10,000.
'Hammer blow'
Businesses reacted with incredulity.
"The renewed 'work from home' order during the most important trading period of the year is a hammer blow for our retail and leisure tenants," said Jace Tyrrell, chief executive of New West End Company.
While many businesses adapted well to working from home, sectors such as hospitality, entertainment and travel have been hit by huge losses. Unlike previous lockdowns, a furlough job support scheme is also no longer available.
A poll from Savanta ComRes also suggested some people may be less willing to follow new restrictions following the revelations around the Downing Street party.
A leaked video showed senior staff laughing and joking over how to explain a gathering in Downing Street during a Christmas Covid-19 lockdown last year. Johnson has apologised.
The prime minister also said Covid restrictions could not last forever and the country may need to have "a conversation" about what to do when a substantial proportion of the population refuses to get a vaccine.
Scotland, Wales and Northern Ireland set their own Covid restrictions and had already set tougher rules.
