King Charles III was briefly admitted to the hospital on Thursday for observation after experiencing temporary side effects from his scheduled cancer treatment, Buckingham Palace confirmed.
As a result, his scheduled engagements for Thursday afternoon and Friday were canceled.
“The King has now returned to Clarence House,” the palace stated. “Following medical advice, tomorrow’s planned engagements will also be rescheduled as a precautionary measure. His Majesty extends his apologies to those affected by these changes.”
Since publicly revealing his cancer diagnosis last year, King Charles, 76, has remained under close medical supervision. Although he stepped back from public appearances for about three months, he continued to fulfill essential state responsibilities, including reviewing government documents and meeting with the prime minister.
His health concerns have placed additional strain on the monarchy, which is undergoing a period of transition following the passing of Queen Elizabeth II, who reigned for seven decades. When Charles ascended the throne in September 2022, he faced the challenge of proving the monarchy’s continued relevance in a modern, multicultural Britain—a responsibility that requires both time and energy.
While largely ceremonial, the role of a constitutional monarch is still demanding. Beyond grand processions in full regalia, there are regular meetings with political figures, public engagements, and recognition ceremonies honoring British citizens. In his first year as King, Charles attended 161 official engagements.
His health struggles come at a time when the royal family is already under public scrutiny. The Princess of Wales, Kate Middleton, was also diagnosed with cancer and took more than six months off from royal duties before making a return in late September.
