King Charles III has been seen in public for the first time since a brief hospital stay related to side effects from his cancer treatment.

The 76-year-old monarch was photographed smiling and greeting well-wishers as he departed Clarence House, where he spent the night with Queen Camilla after experiencing what Buckingham Palace described as a "minor bump" in his health journey.

On Thursday, following his weekly cancer treatment session, Charles was hospitalized for observation due to temporary side effects, leading to the postponement of his afternoon engagements, which included meetings with ambassadors at Buckingham Palace.

Buckingham Palace issued a statement confirming the King had returned to Clarence House and would reschedule his diary as a precaution based on medical advice.

Despite the setback, sources conveyed that the visit to the hospital was not a significant health event, characterizing it as a minor occurrence within an ongoing positive recovery trajectory.

It was emphasized that no further health updates are anticipated, with any required adjustments to his schedule being communicated in due course.

The King had been diagnosed with an undisclosed form of cancer in February 2024 and resumed public engagements in April while continuing weekly treatment.

His recent activities included a reception for media and participation in engagements in Northern Ireland, and he is expected to undertake a historic state visit to Italy in 10 days.

This trip is notable as Charles is set to become the first British sovereign to address both houses of the Italian parliament.

In recent months, Charles has maintained a busy schedule, seeing his public duties as beneficial to his overall well-being.

His efforts in public engagements followed a challenging year for the royal family, which included significant health challenges for both the King and the Princess of Wales, who is now in remission and gradually returning to her royal duties.
