The King has cancelled his royal engagements on Friday after he “required a short period of observation in hospital”, Buckingham Palace has said.
Charles visited the London Clinic – where he was treated for an enlarged prostate in January 2024 – on Thursday morning after experiencing side effects from his cancer treatment.
In a statement, Buckingham Palace said the King has now returned to Clarence House but has received medical advice to reschedule his planned engagements for Friday.
“Following scheduled and ongoing medical treatment for cancer this morning, The King experienced temporary side effects that required a short period of observation in hospital,” the statement said.
“His Majesty’s afternoon engagements were therefore postponed. His Majesty has now returned to Clarence House and as a precautionary measure, acting on medical advice, tomorrow’s diary programme will also be rescheduled.
“His Majesty would like to send his apologies to all those who may be inconvenienced or disappointed as a result.”
It is understood the side effects, of which specifics have not been disclosed, were temporary and not uncommon with many medical treatments.
He travelled to and from the hospital by car and was not joined by the Queen during his brief stay.
The King is said to be on good form at home in Clarence House where is working on state papers and making calls from his study.
A Buckingham Palace spokesperson said: “His Majesty was due to receive credentials from the ambassadors of three different nations this afternoon.
“Tomorrow, he was due to undertake four public engagements in Birmingham, and is greatly disappointed to be missing them on this occasion.
“He very much hopes that they can rescheduled in due course and offers his deepest apologies to all those who had worked so hard to make the planned visit possible.”
