A royal biography has recently revealed a touching story about the late Prince Philip and his grandson, Prince William.

Despite the former Duke of Edinburgh’s occasional grumpiness, Prince William possessed a special talent that could effortlessly shift his grandfather’s mood from sour to cheerful, a quality that Queen Elizabeth II deeply valued.

The queen was always appreciative when Prince William managed to lift Prince Philip out of his cantankerous moods.

Prince Philip, who passed away in April 2021 at the age of 99, found solace in the company of his grandson, William, who had a remarkable ability to bring a smile to his face.

According to Ingrid Seward’s new book, My Mother and I, the queen cherished the moments when William could make Prince Philip laugh.

Even during their duck hunting expeditions, Prince William never failed to brighten his grandfather’s spirits and pull him out of his grumpy demeanor.

After spending quality time with William, Prince Philip would return home in a more cheerful disposition, much to the queen’s delight.

Although not overflowing with joviality, he was no longer in a sour mood, a transformation that did not go unnoticed by Queen Elizabeth.

Prince Philip played a significant role in mentoring Prince William for his future role as king.

During William’s schooling at Eton College, Prince Philip suggested arranging lunches for the young prince with the queen to discuss matters related to his future as a monarch.

Royal historian Robert Lacey highlighted Philip’s instrumental role in guiding William for his future responsibilities.

The idea of William meeting with the queen for important discussions stemmed from Prince Philip’s belief in preparing the next generation for their royal duties.

In a sweet parallel, it is speculated that a similar pattern may emerge with Prince George, William’s eldest son and heir apparent.

Reports suggest that Eton College is being considered for Prince George’s education, mirroring the setup where he would meet with King Charles III, his grandfather, for mentorship sessions at Windsor Castle.

Fond memories of Prince Philip continue to resonate with Prince William.

During a visit to Northern Ireland in 2023, William fondly recalled his grandfather’s straightforward approach in persuading politicians to allocate funds for a building.

His recollection of Philip’s direct language and impactful statements left a lasting impression on William, evoking a sense of pride and nostalgia for his beloved grandfather.
