Covid safety fears have caused the Queen to cancel plans to travel to Sandringham and spend Christmas at Windsor Castle.
The Norfolk estate is where the monarch usually spends the festive season.
But according to The Mirror, Royal sources have said the decision was a "personal one after careful consideration and reflects a precautionary approach."

This will also be the Queen's first Christmas without her husband of 73 years, the Duke of Edinburgh, after Philip's death earlier this year.
Her Majesty's decision to stay in Windsor comes as the UK experiences a sharp spike in Covid-19 cases as the Omicron variant sweeps the land.
Experts have warned there could be up to 6,000 deaths a day if the Government fails to act, after coronavirus cases hit an all-time high on December 17 when 93,045 cases were logged.
Prime Minister Boris Johnson has said his Government is monitoring Omicron levels "hour by hour" but has so far refused to implement new restrictions.
It has been a tradition for the Queen to spend Christmas with her family at Sandringham for many years.
However, the Mirror previously reported how her plans were thrown into disarray by the latest wave of Covid.
Her Majesty had already cancelled her pre-Christmas lunch for extended family.
A senior palace source said: “The pre-Christmas family lunch will not be going ahead.
“The decision is a precautionary one as it is felt to put too many people’s Christmas arrangements at risk if it went ahead.
“While there is regret that it is cancelled, there is a belief it is the right thing to do for all concerned.”
The Government's coronavirus interactive map shows that 45 cases have been recorded over seven days around the Sandringham estate.
This is up 246% on the week before and means the area has an infection rate of 662.7 cases per 100,000 people.
Omicron cases are spreading so fast in the UK that the Covid map is now being updated with a new colour to show spiralling infections.
