The Queen has flown to Sandringham for a weekend break after doctors ordered her to rest.
The 95-year-old left Windsor Castle on Thursday and took a helicopter to her country estate in Norfolk.
The monarch has been undertaking a period of rest after she had preliminary tests during a hospital stay last month - her first overnight stay at a medical facility in eight years.

She has been allowed to carry out light duties from her desk, and this week recorded a video message for world leaders at Cop26.
There has been concern for the Queen given her advanced years, but medics see the two-week period of rest, announced last Friday, as a sensible precaution.
In a statement at the time, Buckingham Palace said the monarch would miss the annual Festival of Remembrance staged by the Royal British Legion at the Royal Albert Hall and attended by senior members of the Royal Family.
But the Queen has the “firm intention” of leading the nation in honouring the country’s war dead on Remembrance Sunday on November 14.
Last week, Boris Johnson said the monarch was on "very good form" after having his weekly meeting with the monarch via a phone call.
It is understood her trip to her Sandringham home is a private trip that has been long-planned.
It comes after the Mirror reported that the Queen was “totally committed” to hosting her extended family over the Christmas period.
A royal source told the Mirror: “The Queen had been hoping she would still be able to spend the weekend at Sandringham and was delighted her doctors gave her the all clear to travel.
“Her Majesty is very much looking forward to hosting her family at her Norfolk home for the Christmas holiday and there is much preparation to be done in time to accommodate everyone who has been invited."
On Monday, the Queen issued a rallying cry to world leaders urging them to work together in “common cause” to tackle climate change and “solve the most insurmountable problems” during her video address to the UN climate summit in Glasgow.
In a message played during a welcoming reception for presidents and prime ministers, she said she hoped the summit’s legacy would be that they recognised “the time for words has now moved to the time for action”.
She paid a heartfelt tribute to “my dear late husband” the Duke of Edinburgh for his environmental awareness in raising the issue more than 50 years ago.
In a rare public expression of emotion, the monarch said it was a “source of great pride” the important role he played in encouraging people to look after the natural world.
She added that she “could not be more proud” of the Prince of Wales and Duke of Cambridge who have continued his work.
Charles and the Duchess of Cornwall and the Duke and Duchess of Cambridge, who all attended Cop26, listened to her message, which the Queen recorded on Friday (October 29) at Windsor Castle.
The Queen wore a butterfly brooch as she spoke, seated in front of a photograph of Philip admiring butterflies in Mexico in 1988.
