King Charles III briefly hospitalised for observation following side effects from cancer treatment

His engagements for Thursday afternoon and Friday were canceled.

“His majesty has now returned to Clarence House and as a precautionary measure, acting on medical advice, tomorrow’s diary program will also be rescheduled,’’ the palace said. “His majesty would like to send his apologies to all those who may be inconvenienced or disappointed as a result.’’

The king’s health has been closely watched ever since early last year when he announced that he had been diagnosed with an undisclosed form of cancer. Charles, 76, stepped away from public duties for about three months but continued fulfilling state duties, such as reviewing government papers and meeting with the prime minister.

Charles’ cancer diagnosis has heaped pressure on the British monarchy, which is still evolving after the 70-year reign of the late Queen Elizabeth II.

When he succeeded his mother in September 2022, Charles’ task was to demonstrate that the 1,000-year-old institution remains relevant in a modern nation whose citizens come from all corners of the globe. But this task takes much time and energy.

Although the duties of a constitutional monarch are largely ceremonial, the royal whirl can be exhausting. Besides the occasional procession in full royal regalia, there are meetings with political leaders, dedication ceremonies and events honoring the accomplishments of British citizens. That added up to 161 days of royal engagements during Charles’s first year on the throne.

Charles’ illness came as his daughter-in-law, Kate, the Princess of Wales, was also diagnosed with cancer. Kate, the wife of Prince William, took more than six months off before returning to public duties in late September.
