The Queen’s royal Christmas will be a very different affair this year.
Traditionally, the royal family descend en masse to the Sandringham estate for a festive stay with the monarch.
But, like the rest of the nation, the Queen and her relatives will have to carefully chose who to have in their Christmas bubble, and where to stay.
Under a relaxation of the coronavirus rules, three households can mix from December 23 to 27, but the bubble must be exclusive over the five-day period, meaning people cannot shift from one group to another.
The Queen and the Duke of Edinburgh, however, have a large family of four children and eight grandchildren, who are all nearly grown up, along with eight great-grandchildren.
Last year, those joining the monarch in Norfolk included the Prince of Wales, the Duchess of Cornwall, the Duke and Duchess of Cambridge, Prince George, Princess Charlotte and Prince Louis, the Duke of York, Princess Beatrice and her then fiance Edoardo Mapelli Mozzi, the Princess Royal and the Earl and Countess of Wessex.
It is understood the decision on where and with whom the Queen will spend the Christmas period will not be made for another few weeks.
The royals will also have to decide whether it is wise to visit the 94-year-old monarch and 99-year-old Philip.
Prime Minister Boris Johnson has warned families they must make a “personal judgment” about the risks of coronavirus to vulnerable loved ones.
Options could include the Prince of Wales and the Duchess of Cornwall joining the Queen as one third of her bubble.
But this would mean Camilla would be unable to see her children and grandchildren.
The Queen may invite her youngest son Edward, with his wife Sophie and their children Lady Louise Windsor, 16, and 12-year-old Viscount Severn, who form one household.
The Princess Royal might attend instead or the Duke of York, but they both have grown-up children, with whom they might form a bubble with.
Adding the Queen and Duke of Edinburgh could mean four households in each case as Princess Anne and Prince Andrew both have two children.
William and Kate with George, Charlotte and Louis could join Charles and Camilla and the Queen and Prince Philip.
That arrangement might work well as the Duke and Duchess of Sussex, who are grieving the loss of their second child after a miscarriage, are thousands of miles away living in the US and unlikely to be returning to the UK, let alone joining the Queen’s bubble.
William and Kate could also easily spend Christmas with the Middleton family in Berkshire.
However Carole and Michael Middleton have two other children as well as Kate – Pippa Matthews and James Middleton, meaning one of the three offspring would not be allowed to gather for the festive celebrations.
The restrictions also mean the Queen will not be able to host her traditional pre-Christmas lunch at Buckingham Palace when the wider royal family usually gathers each year for a get-together a week or so before Christmas.
Rules allow the monarch and Philip to move to Sandringham during the five-day period.
But they could decide to stay at Windsor Castle, where they have spent much of lockdown being looked after by a reduced number of staff dubbed “HMS Bubble”.
If the Queen remains at Windsor, it would be the first time in more than 30 years that she has spent Christmas at the historic Berkshire castle.
During the 1960s, when the Queen’s children were young, many Christmases were celebrated at Windsor.
But since 1988, when the castle was being rewired, royal Christmases returned to Sandringham.
Wherever the Queen is, she can be expected to attend church on Christmas Day.
The monarch is head of the Church of England and has a deep Christian faith.
Places of worship can open in England in all areas from December 2, and people can also meet their Christmas bubble there between December 23 and 27.
It is unlikely the well-wishers who gather to see the royals each December 25 will be able to do so, in a bid to avoid crowds and the spread of coronavirus.
Queen’s chef shares Royal Family’s recipe for Christmas pudding
After a morning visit to church, the family traditionally indulge in turkey, reared at Sandringham, before settling down to the Queen’s Christmas Speech.
The Queen’s address is recorded in advance – but it will be the first time a Christmas broadcast has been carried out amid such unprecedented restrictions and unusual times.
The monarch will take any changes in her stride – she has already delivered two rare addresses to the nation during the pandemic.
Her first televised speech during lockdown in April took place at Windsor in a large room to allow sufficient distance between the Queen and the sole cameraman, who was dressed in PPE and was the only other person in the room.
All other technical staff were in another room connected by speakers.
The Queen is a consummate professional at public speaking and is known for recording her December 25 address in just one take.
The broadcast is a traditional feature of the festive season where the head of state can express her thoughts about the past year.
She will no doubt use her address to focus on the challenges that have faced the nation and Commonwealth in 2020 during the Covid-19 crisis and how the country has responded, as well as drawing on her faith.
The speech is written by the Queen herself and is one of the rare occasions when she does not turn to the Government for advice and is able to voice her own views.
Buckingham Palace declined to comment on the family’s plans for this year.
