Prince William and Kate Middleton expanded their official roles at Buckingham Palace in 2025 as King Charles III curtailed his public schedule during ongoing cancer treatment. The 76-year-old monarch received his cancer diagnosis in February 2024 following treatment for benign prostate hyperplasia, leading his heir to assume approximately 80% of sovereign duties across the United Kingdom.

Succession order establishes future leadership roles

Prince William stands first in line to the British throne, followed by 11-year-old Prince George, who attended five official royal engagements during 2024. Princess Charlotte and Prince Louis hold the subsequent positions in the royal order of succession. Prince Harry occupies the fifth spot in the royal hierarchy, preceding his children Archie and Lilibet.

King Charles III previously took the throne at age 73 in September 2022 after Queen Elizabeth II completed 70 years on the throne. The monarch now focuses his daily calendar around specialized medical treatments that limit international travel.
