King Charles postpones visit after temporary side effects of ongoing cancer treatment

King Charles III has cancelled his public engagements for Friday after experiencing temporary side effects during ongoing cancer treatment, Buckingham Palace says.

The side effects required a short period of observation in hospital, it added. The King has now returned to Clarence House.

Charles had planned to travel to Birmingham for a busy schedule of engagements on Friday, which included a tour of the city’s Royal Ballet.

The palace first announced the King’s cancer diagnosis in February 2024.

A Buckingham Palace spokesperson said meetings with three ambassadors on Thursday were also affected.

“Tomorrow, he was due to undertake four public engagements in Birmingham and is greatly disappointed to be missing them on this occasion,” the palace’s statement added.

“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.”
