The King has overtaken his younger sister to be named the hardest-working member of the Royal family in 2025, despite undergoing weekly cancer treatment.
He conducted more engagements last year than the industrious Princess Royal, including traversing the country, hosting three high-profile state visits and travelling to Italy, Canada and Poland.

An analysis of engagements recorded in the Court Circular found that between them, the 10 working royals managed 23 per cent more jobs in 2025 than in 2024, a year in which both the King and the Princess of Wales were diagnosed with cancer.
Analyst Patricia Treble described the King as “indefatigable” and said that as the year progressed, “it felt like the House of Windsor was making up for lost time”.
Her research found that the King had conducted 533 engagements in 2025, while his sister conducted 478, although she worked on more days overall – 186.
Following closely behind were the Duke and Duchess of Edinburgh (Prince Edward and wife Sophie), who had 313 and 235 engagements respectively.
Next came Queen Camilla, who kept busy with 228 engagements, and the Duke of Gloucester (Prince Richard, cousin of the late Queen Elizabeth II), who ploughed on with little fanfare, conducting 212 engagements.
The Duke, who at 81 is the second-oldest working member of the royal family, outpaced William, Prince of Wales, who carried out 202 engagements in 2025, up from 139 the previous year.
Birgitte, the Duchess of Gloucester, 79, held 113, while the Duke of Kent (another Prince Edward, a cousin of the late queen), 90, conducted 77 engagements in the year he lost his wife, the Duchess of Kent, who died at 92 in September.
