Princess Catherine and King Charles have maintained a close and personal relationship, reminiscent of the one King Charles shared with the Queen. King Charles has expressed his belief in Catherine's important role in the monarchy since her marriage to Prince William, considering her an essential member of the Royal Family. Despite recent health issues, Princess Catherine has consistently demonstrated her loyalty to the monarchy and the royal family. In recent weeks, royal enthusiasts have seen her return to public activities, including appearances at Trooping the Colour and Wimbledon.

However, an interesting revelation from Prince Harry's memoir, "Spare," sheds light on a strange request King Charles made to Catherine a few years ago. In his best-selling book, Harry revealed that King Charles had previously asked Catherine to change the spelling of her name to reduce confusion with the royal code, as both he and Queen Camilla used a "C" with a crown on top. He suggested that she write her name as "Catherine" with a "K". However, Catherine politely declined the unusual suggestion, which did not affect her close relationship with King Charles.

Harry recounted the moment in his book, noting that there were already two royal codes with a "C" and a crown for King Charles and Queen Camilla, making the introduction of another code with a "K" confusing. He expressed curiosity about what happened to the suggestion. Prince William's response was neutral, reflecting the sensitive nature of the discussion, especially as senior members of the royal family unite after Harry and Meghan Markle's departure. This year, both Charles and Catherine have faced their own health challenges.

Despite the name suggestion, Charles' support for Catherine has remained steadfast, especially following the announcement of her cancer diagnosis. He publicly praised her courage in an emotional video message. Former royal correspondent Jenny Bond highlighted the depth of their relationship, referencing Charles' affectionate remarks in her statement following Catherine's announcement. She noted that he described being in "the closest" contact with his beloved daughter-in-law, which underscored their bond.

Their bond has grown stronger as they have both faced challenges. Bond noted that their shared experience with cancer has further strengthened their already strong bond, noting the touching image of Charles visiting Catherine while they were in hospital. A particularly important moment occurred when Charles and Catherine had an intimate lunch at Windsor Castle. The lunch deeply touched King Charles, further cementing their relationship. He treated Catherine as a daughter, showing that they had much to offer each other in their personal journeys. The relationship between Princess Catherine and King Charles is a testament to their mutual respect and unwavering support, illustrating the resilience of the royal family in difficult times.
