Prince William is set to lead the public tributes to his father, King Charles, over the coronation weekend.

A day after he pledges allegiance to the King at the coronation service in Westminster Abbey, the Prince of Wales is set to make a speech in the monarch’s honor at the star-studded Coronation Concert at Windsor Castle.

The “heartfelt” address next Sunday, according to the Daily Mirror which broke the story, would praise King Charles as a man who had “devoted himself to duty and the causes he believed in.” Prince William, 40, could also pay tribute to Queen Camilla for bringing his father happiness, the paper reported.

Buckingham Palace and Kensington Palace, where Prince William has his office, declined to comment on the story.

Prince William’s speech would echo his actions at the Platinum Party at the Palace, which took place in June 2022 as part of the celebrations of his late grandmother Queen Elizabeth’s historic 70 years on the throne. There, he spoke about how “proud” he was of his father and late grandfather Prince Philip for their conservation work spanning decades. The environment is a key part of William’s public work, centered mostly on his groundbreaking Earthshot Prize.

During the May 6 ceremony, Prince William will kneel before his father, place his hands between his father’s and vow to serve him by saying: “I, William, Prince of Wales, pledge my loyalty to you and faith and truth I will bear unto you, as your liege man of life and limb. So help me God.”

The Prince of Wales’ words — called the Homage of Royal Blood — are reminiscent of the homage made by Prince Philip to Queen Elizabeth at her 1953 coronation when he also vowed to be her “liege man of life and limb.”
