Princess Kate, Kate Middleton who is famously close to her family of origin and blood relatives, has established an unbreakable, strong friendship with Sophie, Duchess of Edinburgh, over the past few years.
The friendship, born from an informal mentorship set up by Queen Elizabeth II at the time of Kate Middleton’s wedding to Prince William, has emerged as one of the monarchy’s fiercest alliances.

Upon entering the Royal Family, Catherine, Princess of Wales, faced the unique pressure of navigating public life. Recognizing these pressures, Queen Elizabeth II enlisted the help of Sophie-an insider who had years of experience in the Royal Family and a background similar to Kate’s-to guide her on public royal life, and in turn, a sisterly bond was forged between the two.

Ingrid Seward, an author of royal biographies, commented on their relationship saying:
“They have a sisterly bond, and Sophie is like the older sister Kate never had… They are both protective of their children and Sophie knows what it is like to navigate that world while raising a young family.”

Key Traits Strengthening Their Sisterly Bond.
*Non-aristocratic roots: Both Kate and Sophie came from ordinary, middle-class family backgrounds before marrying into the royal family.
*Long courtships: Both royals were in lengthy romantic relationships with their future spouses before entering the Royal Family, giving them a clear understanding of the marriage itself and public royal life.
*Parental approach: Both share a profound concern that their children remain out of the intense public spotlight.

A Strong Foundation Behind Palace Walls:
The affection they share is obvious during their public appearances; during the Remembrance Sunday memorial at the Cenotaph balcony, the Duchess placed a comforting hand on the Princess’s back, which has been cited by royal observers worldwide as evidence of the support network in place around the Princess of Wales.
Analyst Robert Jobson remarked that the glance they shared and physical touch demonstrated a clear ‘protective bubble’ around the Princess as she continued her royal engagements. The pair’s supportive presence is made even more evident by the fact that Sophie and Prince Edward took on much of the public royal duties for the monarchy while the Princess was away for recovery.
Beyond the palace walls, there is an immense ease with which they spend time together due to the proximity of their current living situations:
The Wales family are currently residing at Adelaide Cottage, within the Windsor Castle estate.
The Edinburghs are at Bagshot Park, which is located just 11 miles away, in Surrey.

This ensures they can spend quality time with one another away from the public eye and that both their children remain close. It’s not just their bond that has proven to be a family trait however; Princess Charlotte is understood to be equally close to the Duchess Sophie, and even her daughter, Lady Louise Windsor.
