How much the Queen, 95, will be able to do by then is unclear.
She is still under doctor’s orders to stick to light duties for the foreseeable future because of an unexplained health condition that led to her spending 24 hours undergoing preliminary investigations last month.
It also forced her to pull out of attending a series of highprofile events.
This week she has had a busy few days, holding a range of in-person meetings and virtual audiences.
Next year she is likely to mark her accession, and a landmark 70 years on the throne, at Sandringham on February 6.
But it is always a day of quiet contemplation for her because it is the anniversary of her father King George VI’s death.
Events at Buckingham Palace are due to begin in April.
But all plans could be thrown into disarray if the new South African Covid variant hits Britain.
One source said: “It’s difficult to plan anything for certain at the moment.”
A palace spokesman said: “The family’s Christmas plans are a private affair.”
