In the late summer of 1995, the most famous woman in the world began slipping away from her own life. Diana, Princess of Wales, was thirty-four, separated from the Prince of Wales, and still more than a year away from the divorce that would formally end her marriage. She lived at Kensington Palace, spent half her weeks with her sons, and the other half on podiums as the most watched charity worker on the planet. When the cameras went off, she went home to rooms that were very quiet.
She had loved men from her own world—a cavalry officer, an art dealer—and each had ended badly. What she told her healer, Simone Simmons, was that she wanted something different now. She wanted a man who was not from her world, someone to whom her title meant nothing. It was close to an impossible wish for a woman who could not walk into a room without being recognized.
Then, on a bank holiday Monday at the end of August 1995, she walked into the Royal Brompton Hospital in Chelsea to visit a friend whose husband had undergone heart surgery. She left having noticed a tall, tired surgeon in scrubs who had not seemed to notice her at all. His name was Hasnat Khan. He had been born in 1958 in Jhelum, in the Punjab in Pakistan, the son of a glass factory owner and a traditional Pashtun matriarch.
He had trained in medicine in Pakistan, worked in cardiology in Lahore, and traveled through Sydney to London, where by the summer of 1995 he was a registrar in cardiac surgery working under Sir Magdi Yacoub, the Egyptian-born surgeon who had built Britain’s heart and lung transplant program. Khan worked ninety-hour weeks, lived in a small rented flat, smoked, read, and was entirely unimpressed by rank. Diana was drawn to him. A fortnight after they met, they drove north together toward Stratford-upon-Avon to visit one of his uncles.
It was an ordinary outing, the sort of thing she had not been able to do for years without a convoy. For Diana, being looked past was a kind of miracle. She told Simone Simmons soon afterward that she thought she had met her Mr. Wonderful.
The hospital became the anchor of their secret. A hospital has private corridors and staff entrances built to keep the public out, and Khan learned to bring her in and out through the service doors. For three weeks that September, she returned almost every day, arriving to sit at the bedside of the recovering patient, then finding her way to the surgeon. At Kensington Palace, her butler Paul Burrell smuggled Khan into the grounds hidden in the boot of a car and carried messages between them.
Then there was Khan’s own flat, a small rented place in Chelsea. Diana would drive herself there late at night, a wig over her hair, and let herself in. Inside, she washed his dishes and folded his laundry. Those closest to her described her delight in the sheer ordinariness of it.
Through the autumn and winter of 1995, the relationship deepened. Diana began to read about his faith, to learn about his work, and to imagine a life in which the hidden country became the whole of it. She stopped planning a love affair and started planning a marriage. She sent her butler to sound out a Roman Catholic priest about the possibility of a private wedding, away from the eyes of the world.
She began to study the Quran and spoke with a London imam about the practicalities of a marriage across two religions. When stories surfaced in 1996 that she might convert to Islam, she denied them publicly. The likelier truth is that she was a woman in love with a Muslim man, trying seriously to understand the world he came from because she meant to enter it. But there was a difference between them that would show its teeth.
For Diana, marrying Khan meant escape, ordinariness, peace. For Khan, marrying Diana meant the opposite: the end of the anonymity that let him do his work, photographers outside the hospital, his family named in newspapers, his ninety-hour weeks fractured by attention no surgeon could survive. She was reaching toward his world because it promised her freedom. He was staring at hers and seeing a cage.
Before the world could break them, Diana had to win over the one person whose blessing she believed she needed most: his mother, Naheed Khan. A traditional Pashtun matriarch, Naheed had a settled idea of the wife her eldest son should take. That wife would be Pakistani, from the right background, married in the right way. An English divorcee, a Christian, the most photographed woman on the planet, was very close to the opposite of everything she had in mind.
Diana’s path ran through an unlikely bridge: Jemima Goldsmith, who had married Hasnat’s distant cousin Imran Khan in May 1995. Jemima would later write that for a son to marry an English girl was every conservative Pashtun mother’s worst nightmare. Diana went to Pakistan in February 1996 and again in May, staying with Imran and Jemima and publicly raising money for Imran’s cancer hospital in Lahore. On the May visit, she went to the Khan family home in Model Town and took tea with Naheed and the elderly women of the family.
She had not warned Hasnat she was going to do this, and when he learned she had gone to his family behind his back, he was outraged. She was trying to open a door. He knew the door was not hers to open. She made a quieter visit in May 1997, and still Naheed’s position did not move.
Blocked from the front, Diana did the one thing that broke the relationship. According to accounts from two of her biographers, she went to Khan’s employer, Sir Magdi Yacoub, and tried to arrange a transplant post for him abroad, most often named as Australia, where the two of them might live with far less scrutiny. On its face, it was an act of love. But to Khan, a private, self-made man allergic to being managed, it must have felt like the whole danger of loving Diana made concrete.
His career was the spine of his life. She had gone without asking him to his own boss to arrange his professional future for him. The transplant post was never the real issue. The episode showed him exactly what marriage to her would feel like.
He had a settled conviction, one he would state plainly years later under oath, that a public life beside Diana would be unbearable. His main concern about marrying her, he said, was that his life would be hell because of who she was. He never questioned her loyalty. What he questioned was the world, and whether it would ever let a surgeon and a princess marry and then be left alone.
He did not say no because he stopped loving her. He said no because he had looked with a surgeon’s cold honesty at what a public life beside her would do to his work, his family, his patients, and his sanity, and judged it unsurvivable. On the 26th of January 1996, the Sunday Mirror ran the story on its front page, naming for the first time Hasnat Khan’s connection to Diana. It reported on evenings the couple had spent together and dinners at a Greek restaurant near Stratford-upon-Avon, including one meal that ran four and a half hours.
For Khan, the headline was proof of the future he feared. A cardiac surgeon holds lives in his hands on an almost daily basis. He understood that a man who could not walk from his car to the hospital doors without a scrum of photographers was a man who could not do that work properly. By the early summer of 1997, the decision had been made.
Diana ended the relationship in two meetings in the period just after she had returned from time spent with the Al-Fayed family. By Khan’s account, she told him it was all over between them and denied there was anyone else. He did not, at that point, know about Dodi Al-Fayed and learned of that relationship only when he heard the news on the radio. He later came to believe Diana had finally realized that Dodi could give her all the things he could not: openness, ease, a willingness to live a public life beside her.
He understood that his refusal had left a space, and that another man had stepped into it. Within weeks of leaving the surgeon, Diana was photographed on a yacht with another man. In late July 1997, she joined the Fayed family on holiday near Saint-Tropez. Where the relationship with Khan had been built entirely in shadow, this one unfolded almost entirely in light.
There were paparazzi, a yacht called the Jonikal, long-lens photographs sold around the world. Diana, who had spent two years perfecting the art of not being seen, now moved through her days in full view. In the early hours of the 31st of August 1997, Diana and Dodi were being driven through Paris in a Mercedes, pursued by photographers, when the car crashed in the tunnel beneath the Pont de l’Alma. The driver, Henri Paul, and Dodi Al-Fayed died at the scene.
Diana, gravely injured, was taken to the Pitié-Salpêtrière Hospital, where she died. She was thirty-six. On the 6th of September 1997, among two thousand mourners inside Westminster Abbey, one man in dark glasses said nothing at all. Hasnat Khan was there, the man Diana had wanted to marry, sitting among the invited mourners.
The funeral drew a television audience of roughly 32. 1 million in the United Kingdom and an estimated two to two and a half billion worldwide. More than a million people lined the route through London. And somewhere inside the Abbey sat the one man in the building who had known her not as a princess, but as a woman who did his washing up at midnight, and he could tell no one.
Diana was buried afterward at Althorp, the Spencer family estate, on a small island in an ornamental lake, reachable by no crowd, watched by no lens. For the rest of his life, Khan sold nothing. He gave no interviews trading on the relationship, wrote no book, and mostly declined to correct or confirm what others said. He spoke twice when the machinery of the state required it: a police interview in 2004, and a written statement to the inquest in February 2008, in which he gave a spare and gentle account of their time together.
The inquest returned its verdict on the 7th of April 2008, finding that Diana and Dodi had been unlawfully killed through the negligence of their driver and the pursuing photographers. Khan’s testimony helped lay to rest the wilder theories. His life went on. He kept operating at the Royal Brompton and other London hospitals, resigned in 2007 to lead a cardiac unit in Malaysia, returned to a consultant’s post in Essex in 2013.
In 2006 his family arranged his marriage to a woman of Afghan royal descent, the marriage his mother had always wanted for him. It ended in divorce within about a year and a half. He married again in later years. In 2013, when a film about the romance was released, he rejected it publicly as based on hypotheses and gossip.
In 2021, after the Dyson report exposed how Martin Bashir had manipulated Diana, he spoke again, saying Bashir had filled her head with rubbish and that she had become fearful and suspicious. In the end, the story is not something that was done to Diana. This chapter was a choice made by two people. She chose a man freely, pursued him, planned a future around him, and he, just as freely, chose to keep the life he had rather than be swallowed by hers.
He did not leave because he stopped loving her. He left because he understood, more clearly than she could, that the world would never have left them alone. She reached for an ordinary life the way a drowning swimmer reaches for shore, and the very thing that made her extraordinary was the current that kept pulling her back. He said it himself years later, with the plainness that ran through everything he ever said about her.
There was no hierarchy in their relationship, he insisted. She was not a princess and he was not a doctor. They were simply friends. It holds the whole story in a single breath.
For a little while, in a world that would not allow it, a woman everyone watched and a man nobody knew managed to be to each other nothing more or less than two people. And then the world, which had never once left her alone, took her back.
