Christmas Covid rules: Who are you allowed to see?

At Christmas, coronavirus restrictions will be eased to allow people to mix with a slightly wider circle of family and friends.

Across the UK, people will be able to form "bubbles" of three households over a five-day period. Who can be in your bubble will depend on where you are.

Between 23 and 27 December, the three households in a "Christmas bubble" can mix indoors and stay overnight.

Northern Ireland has a window of 22 to 28 December, to allow time to travel between the nations.

Bubbles will be allowed to meet each other:

The bubbles will be fixed, so you will not be able to mix with two households on Christmas Day and two different ones on Boxing Day. Households in your Christmas bubble can't bubble with anyone else.

There will be no limit to the number of people who can join a bubble in England, Wales and Northern Ireland, although the English guidance says it should be "as small as possible".

But the Scottish government has said Christmas bubbles should contain no more than eight people. Children under 12 will not count in the total.

The rules about what counts as a household also depend on where you are.

In England if you have formed a support bubble with another household, that counts as one household, so you can join with two other households in a Christmas bubble.

The Scottish government guidance says any Christmas bubble should contain no more than one "extended household".

People who are self-isolating should not join a Christmas bubble. If someone tests positive, or develops coronavirus symptoms up to 48 hours after the Christmas bubble last met, everyone will have to self-isolate.

You will still be able to see other people who are not in your bubble outside your home, subject to the rules of the tier where you are staying.

Travel restrictions will be lifted to allow people to visit their families anywhere in the UK.

But the government has warned that there will not be extra public transport laid on.

It has urged people to plan their travel in advance.

You will not be allowed to go with your Christmas bubble to hospitality settings, such as pubs and restaurants, or to entertainment venues.

You can meet people outside your Christmas bubble, but only outside the home and in line with the tier rules of the area in which you are staying.

Places you can meet include parks, beaches, open countryside, public gardens, allotments and playgrounds.

Scottish First Minister Nicola Sturgeon said the relaxation of restrictions will not be extended to cover New Year's Eve.

She said: "I know New Year is special for people, perhaps slightly more so in Scotland than in other parts of the UK, but the virus is still there."

The planned firework displays in Edinburgh and London have been cancelled.

The virus will not call a truce because it is Christmas, and will be as contagious as at any other time, UK Prime Minister Boris Johnson has said.

Even if it is within the rules, meeting friends and family over Christmas will be a "personal judgement", the government says.

People should consider the risks to themselves and others, particularly those who are vulnerable.

Scotland's First Minister Nicola Sturgeon urged people to use the Christmas rules responsibly and "only if you think it is necessary".

Children aged under 18 whose parents live apart are allowed to be part of two separate Christmas bubbles. This means they can see both parents without being counted as part of another household.

University students may return to their parents in the early December "travel window" and be counted as part of their household straight away.

But if parents have three or more grown-up children who are not at university, then they cannot all form a Christmas bubble with their parents.

Individual households can split for Christmas. So, if three people are sharing a home, they can all go and form separate Christmas bubbles with their families and come back to form a single household again afterwards.

In England, care home residents have been told not to take part in Christmas bubbles, while visits out of the home should only be considered by residents who are of "working age". This is because of the increased risk of the resident catching coronavirus, and spreading it to other vulnerable people when they return, the government says.

People are asked to consider whether visiting at the care home would "provide meaningful contact in a safer way", while residents who do leave will be tested and asked to isolate when they return.
