New images of King Charles III have sparked a wave of concern across Britain — and a scramble inside Buckingham Palace — after the monarch appeared noticeably frail during a joint appearance with Prince William at London’s COP30 climate summit, RadarOnline.com can report.

The 76-year-old King, who has been undergoing cancer treatment since early this year, appeared significantly thinner and paler than in previous public outings.

“His suit was hanging off him,” one insider told #ShuterScoop. “He looked like a man fighting something bigger than he’s letting on.”

Although palace officials maintain that the King is “doing well” and “continuing light duties”, senior royal aides privately acknowledge that the images have caused alarm behind the scenes. “The optics are impossible to spin,” one source admitted.

King Charles’s diagnosis, confirmed earlier this year, has already limited his public schedule. Insiders now suggest that his health challenges may be taking a visible toll. “They’re quietly preparing William to step up — fast,” one senior courtier revealed. “The illusion of perfect health is collapsing.”

While official statements from Buckingham Palace remain upbeat, long-time royal observers are less convinced. “You can’t Photoshop frailty,” said one palace watcher. “What we’re seeing is the reality behind the crown — a monarch in decline.”
