Catherine, the Princess of Wales, is considered a crucial figure for the British monarchy, with royal experts describing her as the institution's "greatest asset." Her public demeanor, resilience through health challenges, and the deepening connection with King Charles III are frequently cited as contributing factors to her indispensable role.
Vanity Fair royal correspondent Katie Nicholl noted that the Princess of Wales has made a seamless transition into royal life, a demanding world that requires significant sacrifice. Nicholl stated that Catherine undertakes her duties with "grace and dignity, always with a smile," earning her widespread respect. The expert also indicated that both King Charles and Queen Camilla hold her in high regard.
A Bond Forged Through Shared Challenges
The relationship between King Charles and the Princess of Wales has reportedly grown stronger since both received cancer diagnoses. Buckingham Palace announced the King's diagnosis in 2024, and in March of the same year, Kate revealed her own cancer treatment. Following chemotherapy, she announced in January 2025 that she was in remission.
British broadcaster Helena Chard observed that King Charles finds inspiration in the Princess of Wales's strength. "King Charles sees enormous value in Princess Catherine," Chard said. "Not just as the wife of his heir, but as the cornerstone of the monarchy itself. He genuinely loves his 'darling' daughter-in-law." Chard added that their shared experience with cancer has created a "deep bond and understanding that goes beyond duty."
Royal author Sally Bedell Smith previously told People magazine that the King views Kate "like the daughter he never had" and shares an impulse with Prince William to protect her.
Evolving Role in a Slimmed-Down Monarchy
With a reduced number of working royals, figures like Princess Catherine are seen as vital to the monarchy's stability. Prince Andrew stepped back as a working royal in 2019, and in 2020, Prince Harry and Meghan Markle, the Duke and Duchess of Sussex, also ceased their senior royal duties.
Author Catherine Mayer noted that "William and Catherine carry the whole thing," suggesting that increased attention and expectations are placed on the Waleses as they prepare for future roles. Royal experts believe the couple is well-positioned to support King Charles.
Richard Fitzwilliams emphasized that the Princess of Wales's value extends beyond her individual strengths, highlighting "her partnership with William and their family." He stated that Catherine fully supports William's approach to family matters, including the ongoing dynamic with Prince Harry.
Public Trust and Dedication to Duty
Princess Catherine's public engagements, including her recent efforts to raise money for cancer research by climbing the three highest peaks in the United Kingdom, have further garnered public support. Nicholl noted that she "has turned her experience into something positive," earning significant respect and affection from the British public.
Royal expert Hilary Fordwich commented on the tangible public appreciation for the Princess of Wales, stating, "She has become indispensable and has won the public’s trust." Fordwich also pointed to the consistency, steadiness, and modern approach Catherine brings to her role, influenced by her upbringing and dedication to duty. The body language between King Charles and the Princess of Wales, according to Fordwich, demonstrates their comfort and ease with one another, partly attributed to their shared experiences during their respective cancer treatments.
