Princess Diana’s Marriage to King Charles Is Well-Documented — But Did You Know Her Sister Also Once Dated the Future King?

The story of Princess Diana’s marriage to King Charles III has been explored extensively over the decades, becoming a defining narrative in modern royal history. Yet, fewer people are aware of an intriguing precursor: the romantic link between Lady Sarah Spencer, Diana’s older sister, and Prince Charles. This lesser-known relationship offers a unique lens into the dynamics of the British aristocracy and sheds light on how a series of personal and public events ultimately shaped the future of the royal family.
The Royal Search for a Bride
During the 1970s, Prince Charles—then the Prince of Wales and heir apparent to the British throne—was widely regarded as one of the world’s most eligible bachelors. As speculation mounted across British society and media about who might become the future queen, Charles enjoyed a robust social life, often in the company of prominent figures and aristocrats. Despite public fascination with his relationships, Charles faced considerable pressure to find a fit and proper bride, both from his family and from the formidable traditions of the monarchy.
Public interest in the prince’s private life intensified after his intermittent relationship with Camilla Shand (later Camilla Parker Bowles, now Queen Camilla). At the time, Camilla was considered unsuitable for royal marriage, partly due to social conventions and expectations concerning background and marital history. Charles, still searching for a partner who matched royal requirements, was soon drawn to Lady Sarah Spencer—eldest daughter of the 8th Earl Spencer and the older sister of Diana.

The Spencers: A Family Close to Royalty
Born in 1955, Lady Sarah Spencer shared her noble upbringing with her siblings: Jane, Diana, and Charles (who would become the 9th Earl Spencer). The Spencers were established members of the British aristocracy, maintaining close ties with the royal family across generations. Sarah, often described as vivacious and intelligent, was very much part of the same elite social circles as Prince Charles.
An interesting aside is that Diana, later famed for her warmth and empathy, once worked as a cleaning lady for her older sister Sarah. This early experience reflected Diana’s unpretentious approach to life—including her employment as a nursery assistant—before her eventual ascension into the global spotlight as a future princess.
The Romance of Lady Sarah Spencer and Prince Charles
In the late 1970s, the British media began circulating rumors of an impending engagement between Sarah Spencer and Prince Charles. Their budding connection was the subject of social speculation, as both belonged to aristocratic backgrounds considered compatible by royal standards. Public sightings of the two together—such as their celebrated ski trip to the Swiss resort of Klosters—fueled further rumors that Sarah might soon receive a proposal from the prince.
However, this promising relationship ended as abruptly as it had begun. The catalyst was a candid conversation Sarah had with journalists Nigel Nelson and James Whitaker following their ski holiday. Speaking frankly, she downplayed the romantic speculation, stating, “It was a marvellous holiday, but there’s no question of an engagement.” She later added, “There is no chance of my marrying him. I’m not in love with him. And I wouldn’t marry anyone I didn’t love whether he were the dustman or the King of England…If he asked me I would turn him down. I would only marry for love.”
The Fallout: Reaction Within the Royal Circle
Sarah’s remarks, subsequently published in the press, caused considerable embarrassment both to the Spencers and the royal family. According to royal biographers, Prince Charles was upset by Sarah’s public comments, which also included personal revelations about her past, such as her brief expulsion from school and her struggle with anorexia. The perceived indiscretion strained her relationship with Charles to a point of no return.
Tina Brown, author of The Diana Chronicles, detailed that Sarah immediately recognized her misstep as soon as she spoke, and her initial efforts to portray her statements as misrepresented only complicated matters. Charles reportedly told her, “You’ve just done something extremely stupid.” The intense scrutiny that comes with any royal connection meant that even a small public misjudgment could have outsized implications for those involved.

New Beginnings and the Introduction of Diana to Charles
The relationship between Lady Sarah Spencer and Prince Charles quietly concluded in 1978. The following year, Sarah married Neil Edmund McCorquodale, establishing her own family life outside the royal limelight. Far from harboring resentment, Sarah played a pivotal role in introducing her younger sister Diana to Prince Charles—a meeting that, in hindsight, altered the course of royal history.
At the time of their introduction, Diana was 19 and worked as a nursery assistant. Their first significant encounter occurred at Althorp House, the Spencer family seat, in the wake of the assassination of Lord Louis Mountbatten, an event that deeply affected Charles. Royal author Penny Junor recounts that, after a polo match, Diana expressed heartfelt condolences to the grieving prince. She reportedly told him, “My heart bled for you when I watched the funeral; I thought, ‘It’s wrong, you’re lonely—you should be with somebody to look after you.’” According to Junor, Diana’s sensitivity struck an emotional chord with Charles, opening the path for their subsequent courtship.
The Marriage of Charles and Diana
Diana’s suitability as a royal bride was apparent to senior members of the royal family—a peerless combination of lineage, public image, and (importantly to the era) her status as a young unmarried woman. The couple’s wedding on July 29, 1981, became an internationally watched event, with the Archbishop of Canterbury famously stating, “Here is the stuff of which fairy tales are made—the prince and princess on their wedding day.”
The union of Charles and Diana brought hope and excitement to the monarchy but, as history has since revealed, was also fraught with challenges and unmet expectations. The marriage produced two sons: Prince William, born in 1982 and now the Prince of Wales, and Prince Harry, born in 1984, both of whom continue to shape the modern narrative of the British royal family. As a tribute to Lord Mountbatten, the name Louis appears in the full titles of both William and his eldest son George.

Family Ties: Lady Sarah’s Ongoing Role
Lady Sarah McCorquodale emerged as a close confidant and lady-in-waiting to her sister Diana through the 1980s and 1990s. Frequently seen at official events and royal tours, Sarah and fellow sister Jane (Lady Cynthia Fellowes) provided essential support to Diana amid the pressures of royal life. These bonds extended to Diana’s children, with both Sarah and Jane maintaining a close relationship with Princes William and Harry into adulthood.
Camilla, the Royal Family, and Historical Change
The complex relationship between Prince Charles and Camilla Shand resurfaced after Charles’s marriage to Diana began to unravel in the 1990s. Camilla, who married Andrew Parker Bowles in 1973, found herself back in the public eye as the royal family’s internal struggles became global news. In 1996, Charles and Diana divorced. The following year, in a tragic car accident in Paris, Diana lost her life at age 36—sending shockwaves across the world and further transforming the public’s relationship with the monarchy.

The Legacy of Lady Sarah Spencer
In the wake of Diana’s death, Lady Sarah became president of the Diana, Princess of Wales Memorial Fund, overseeing its charitable initiatives until 2012. Now 68 years old, she continues to honor her sister’s legacy and participates in family and public events, particularly those involving Diana’s children.
The course of royal history might have charted a very different direction had Lady Sarah remained close to Prince Charles and eventually married him. The connections and events that led from Sarah’s relationship with Charles to Diana’s marriage and the ripple effect on British society and monarchy remain a vivid testament to the unpredictable nature of personal relationships within the world’s most recognized royal family.
Societal Impact and Continuing Public Fascination
The marriages, relationships, and personal journeys of the Spencer sisters have left a lasting impression on British popular culture and the evolving perception of the royal family. From the initial speculation surrounding Charles’s prospective brides to the tragedy of Diana’s passing—and the resilience shown by figures like Lady Sarah—the public continues to engage with their stories in media, biographies, and documentaries.
Today, Lady Sarah and her family maintain private lives but remain involved in charitable activities and public occasions. Their legacy continues, both through the ongoing work of Diana’s sons and in the collective memory of a public deeply moved by the triumphs and tragedies of the Spencer and Windsor families.
Conclusion: A Story of Fate and Family
The intertwined lives of the Spencers and the British royal family offer a compelling account of tradition, romance, and the weight of public attention. The story of Lady Sarah Spencer and Prince Charles is more than a historical footnote—it represents the intricate interplay between personal choice and societal expectation. Ultimately, it was Diana, with her enduring compassion and sense of duty, who would capture the world’s imagination and help shape the monarchy’s future. Yet, it was Sarah, through her connection and generosity, who set these momentous events in motion.
