Princess Diana's Hidden Love Affair with Dr Hasnat Khan Revealed in Brother's Memoir Earl Spencer's newly released memoir uncovers the secret romance between Diana and cardiothoracic specialist Dr Hasnat Khan, revealing plans to move to South Africa, interactions with Dr Christiaan Barnard, and Khan's recent public appearance in Pakistan. The story explores the princess's search for escape from royal scrutiny and her dramatic life choices. Princess Diana's secret romance with heart surgeon Dr Hasnat Khan has exploded into public view after her brother Earl Spencer unveiled a trove of details in his memoir, Swan Song: Diana My Sister. Diana Plotted South African Escape With Hasnat KhanThe book claims that Diana, already estranged from Prince Charles, plotted to leave the United Kingdom and start a new life in South Africa with Khan, a cardiothoracic specialist who had earned the nickname "Mr Wonderful" in her eyes. According to Spencer, the princess even reached out to Dr Christiaan Barnard, the pioneer of heart transplantation, while in Cape Town in an effort to secure a position for Khan at a South African hospital.The drama only intensified when the Daily Mail, in April, reported that Khan had been appointed dean of the Jinnah Institute of Cardiology in Lahore, Punjab, Pakistan, marking his return to his homeland. Yet, just days after the publication of Spencer's book, Khan appeared publicly on Pakistani television beside Punjab chief minister Maryam Nawaz, proudly guiding her through the newly inaugurated 250‑bed heart transplant centre named after Nawaz.At the ceremony, he was seen in a grey suit, leading her around the cutting‑edge facility and demonstrating his role as an educator and administrator. The England‑Pakistan connection may be a fascinating footnote, but the real story is the extraordinary love that developed between a grieving princess and a humble doctor. Dr Khan recalls meeting Diana at the Royal Brompton Hospital in Chelsea, where she was visiting a friend undergoing treatment.Romance Blooms Between Princess And Heart SurgeonHe later reflected that they had struck up a friendship almost by accident; during a random encounter at his unit, Diana asked if he would accompany her to her uncle's house in Stratford‑upon‑Avon, and the rest, as they put it, was history. In the days that followed, the pair would share quiet dinners at the Breakspear Arms pub near Harefield Hospital, a far cry from the glitz of Buckingham Palace.Diana, still married to Charles at the time, allegedly smuggled the doctor into Kensington Palace by hiding him in her car boot, a detail that raises the stakes of their clandestine relationship. Spencer's memoir also paints a portrait of Princess Diana's desperation to escape the spotlight. He describes a series of hypothetical plans that Diana would entertain, including staying in a rural South African getaway, or living near Groote Schuur Hospital (the site of the world's first heart transplant).Plans Collapse As Diana Moves Toward Dodi FayedBarnard's response, according to the book, was to investigate potential opportunities for Khan, but the plans ultimately collapsed, forcing Diana to reassess her next moves. The story reaches a tragic apex as Diana appears to pivot toward a new relationship with Dodi Fayed. Historians note that the two, 1997, eventually died in a car crash in Paris.Today, the narrative forces us to re‑examine an era of royal intrigue, medical advancement, and a princess who dared to love outside the palace walls. While Dr Khan has chosen to keep most of his personal life private, the public is now left to wonder how the story of love, ambition, and tragedy between Diana and the South African‑born surgeon will endure in the annals of history.
