Buckingham Palace has expressed concern over King Charles III’s declining health as reports emerge about his alarming weight loss amid his cancer battle.

According to RadarOnline, insiders revealed that the monarch’s noticeable frailty has sparked fears his condition may be worsening. While palace officials continue to project an image of stability, those close to the royal household say the King appears increasingly weak with each passing day.

“He looked as though he was battling something far more serious than it seemed at first glance,” one insider shared.

Sources suggest that behind closed doors, preparations for a potential transition of power to Prince William have quietly begun, as uncertainty grows around Charles’s true medical state. Rumors also claim that official photographs from royal events are being retouched to maintain an image of good health.

“They’re quietly preparing William for a swift transition. The illusion of perfect health is collapsing,” the insider added.

The BBC reported that Shinda, who is receiving prostate cancer treatment, discussed diagnostic delays with the King.

“I’m very sorry about that, it’s so frustrating,” Charles replied, adding, “Half the problem is detecting it, isn’t it, in time.” Later, he said, “The great thing, I think, is they’re getting better and better at dealing with these things. The trouble is there’s always hope down the road.”
