New Covid restrictions have come into force in Scotland, Wales and Northern Ireland as the nations try to halt the surge in infections.
All three nations have introduced curbs on the hospitality and leisure industry, resumed social distancing rules and put limits on the size of gatherings.
Boris Johnson has not announced any further restrictions in England.
But the prime minister said he would not hesitate to act if necessary.
Daily coronavirus figures are not being reported over Christmas Day and Boxing Day, but Friday saw a new high of 122,186 UK cases.
The Office for National Statistics estimated – using its weekly random testing programme – that 1.74 million people, or one in 35, had coronavirus seven days ago. But that was before last week’s big increase in the daily counts, which are based on positive results in tests.
Each of the three nations that has reimposed restrictions has chosen different rules, but they all feature limits on the size of gatherings, requirements for social distancing and tighter rules for pubs, restaurants and leisure venues.
Indoor events will be limited to 100 people standing or 200 people sitting, while outdoor events will be capped at 500 people
- One metre physical distancing will be required at public events
And from 27 December:
- Pubs, restaurants, theatres, cinemas and gyms will have to ensure a one metre distance between groups of people
- Groups of people meeting will be limited to three households
- Table service will be required in hospitality venues offering alcohol
The new restrictions in Wales from Boxing Day mean that:
- No more than six people can meet at pubs, cinemas and restaurants
- Outdoor events are limited to 50 people, and there is a maximum capacity of 30 for indoor events, including in private homes
- Two-metre social distancing is required in offices and public places
- Nightclubs have to close
And from Boxing Day in Northern Ireland, nightclubs must remain closed and indoor standing events are banned.
Then, from 06:00 on 27 December, pubs, cafes and restaurants will have to provide table service only, while no more than six people from different households will be allowed to sit together.
Pubs and restaurants in Wales have said they fear they could be “crippled” by new rules for the industry.
Shaun Barnsley, a pub owner in Chepstow, said his takings for December were already 65% down – and the new restrictions had left him feeling “very, very flat”.
The return to table service has meant more staff were needed and things were not as jolly as they could be, he said, adding: “It’s a struggle.”
The new rules mean that Boxing Day football matches in Scotland’s premiership will be played in front of a maximum of 500 seated fans, while in Wales all large sporting events will be played behind closed doors.
Meanwhile in England, Covid cases have hit the popular Boxing Day football line-up, forcing the postponement of Premiership games between Burnley and Everton, Liverpool and Leeds United and Wolverhampton Wanderers against Watford.
Omicron: What we know so far
- This variant is very contagious – it spreads faster than others and can infect people even if they are fully vaccinated
- Vaccines and boosters are still essential – they do a great job at protecting against severe disease that could put you in hospital
- It is milder – if you catch it, the risk of needing hospital treatment is up to 70% lower than with previous variants – but that is largely because many of us have built up immunity from vaccines and past infections rather than changes to the virus
- Even if Omicron is milder, because it is more contagious a large number of people will catch it and some will still become very ill, which puts pressure on the NHS
