Queen Elizabeth, 95, is back at her desk at Windsor Castle after spending the night in hospital for the first time this year for what Buckingham Palace described as “preliminary investigations”.
The world’s oldest and longest reigning monarch stayed in hospital overnight until Wednesday, but returned to Windsor Castle west of London the following day, officials said she was in good spirits and back at work.
The queen, who canceled an official trip to Northern Ireland on Wednesday, had been told to rest by her medical staff, the castle said, but her condition was not related to COVID-19.
“After medical help to rest for a few days, the Queen went to the hospital on Wednesday afternoon for some initial examinations, returned to Windsor Castle at lunchtime today and is in a good mood,” the palace said late Thursday.
Helpers gave no details of what had prompted the doctor, and some royal correspondents said they hoped the official version of events painted the full picture.
Prime Minister Boris Johnson sent her best wishes, saying the monarch was back at her desk.
“I’m given to understand that Her Majesty is actually characteristically back at her desk in Windsor as we speak,” Johnson told reporters.
A royal source said the queen had been staying at King Edward VII Hospital in central London for practical reasons and that her medical team had taken a cautious approach.
The source said she was now resting and performing light official duties.
Elizabeth – who is the queen of 15 other kingdoms, including Australia, Canada and New Zealand – returned to her desk to work Thursday afternoon and took on some light duties, the source said.
Elizabeth, who ascended the throne when the United Kingdom issued her imperial power, has symbolized stability in generations of British peoples and built the monarchy’s popularity despite seismic political, social and cultural changes that threatened to make it an anachronism.
A quiet and non-committal dedication to duty, even in old age, has earned her widespread respect in Britain and abroad, even from Republicans who are eager for the monarchy to be abolished.
Elizabeth spent Tuesday night hosting a drinks reception in Windsor for billionaire leaders, including Bill Gates, after Prime Minister Boris Johnson convened a green investment conference ahead of the COP26 climate summit.
Elizabeth, along with her son and heir Prince Charles, 72, and grandson Prince William, 39, greeted guests, including the American climate envoy John Kerry without masks.
The queen, wearing a blue-green skirt and jacket with pearls, was photographed next to Johnson, smiling and chatting with guests.
The head of state, who next year celebrates 70 years on the throne, is known for his robust health.
The last time she is thought to have spent a night in the hospital was in 2013, when she was suffering from symptoms of gastroenteritis.
She had successful surgery to treat cataracts in 2018 and a knee surgery in 2003, but royal officials hate to discuss health issues in general.
Prince Philip, her husband of more than seven decades, died in April at the age of 99.
It has not prevented her from performing her official engagements, though her age has meant that she has handed over several duties to Charles and other members of the royal family.
She was seen this month for the first time using a cane for public support except after her knee surgery.
