Buckingham Palace said on Wednesday that Queen Elizabeth II has canceled a planned visit to Northern Ireland on medical grounds.
Royal officials said in a statement that the 95-year-old monarch had “reluctantly accepted medical advice to rest for the next few days”.
Britain’s Domestic Press Association news agency said the decision was deemed not related to the coronavirus and she was resting at Windsor Castle, west of London.
He is also expected to attend events at the United Nations Climate Change Summit to be held in Glasgow next month.
The Queen – Britain’s longest-serving monarch – moved to Windsor in March last year as the coronavirus outbreak escalated.
The decision was taken to self-isolate due to the increased risk of infection due to her age, although she has since been vaccinated.
Since her death at the age of 99 in April, at the funeral of her late husband, Prince Philip, she has resumed public engagement, either alone or with other senior royals.
On Tuesday, she hosted a reception in Windsor for international business leaders attending a government investment summit and received two ambassadors via videolink.
It was also revealed that she had turned down an award celebrating the achievements of older people, assessing that it did not fit the criteria.
“His Majesty believes you are as old as you feel,” his assistant personal secretary replied to The Oldie Magazine, it reported on Tuesday.
Mahal’s latest statement will inevitably spark fears for his health, even if he appears to be in good spirits at Tuesday’s events.
He was first seen using a walking stick at a major public event, although royal officials said it was not linked to any health condition.
“Her Majesty is in good spirits and is disappointed that she will no longer be able to visit Northern Ireland, where she was due to attend several events on Thursday and Friday”, Mahal said.
“The Queen sends her warmest wishes to the people of Northern Ireland, and looks forward to the future.”
A church service is due to take place in the border town of Armagh on Thursday to mark the 100th anniversary of the creation of Northern Ireland.
In 1952 the queen replaced her father, King George VI, and the following year celebrated her platinum jubilee to complete 70 years on the throne.
