King Charles waves as Prince Harry loses UK court case

King Charles III, who's battling cancer, broke the cover moments after his younger son Prince Harry lost High Court security battle.

The monarch appeared shunning news about Harry's UK court case as he waved his well-wishers and smiled to greet them.

The 75-year-old made his first public appearance on Wednesday after Prince William's unexpected decision to cancel his godfather's memorial service at the eleventh hour.

The monarch was photographed in the State Bentley leaving Clarence House this morning ahead of more cancer treatment in the capital.
