Royal transition accelerated: William and Kate take on more with King Charles III’s fragile health

King Charles III, 76, saw his health deteriorate in November 2025 due to cancer diagnosed in February 2024.

The disease, identified during a prostate procedure, shows no signs of remission despite continuous treatments.

Royal officials confirmed that Charles III has drastically reduced his public schedule, participating in fewer than 50 events in 2025, compared to more than 200 the previous year. The monarch holds private meetings and official dispatches, but has delegated international trips and diplomatic commitments to his eldest son.

• Kate Middleton plans around 20 events focused on children’s health.
