Hasnat was a junior surgeon at the Royal Brompton when he first met Diana. The two carried on a secret relationship for two years while Diana was still married to Charles in 1995. Diana would often visit him at the hospital and call him under the pseudonym "Armani." Hasnat is considered to have been the love of Diana's life, and she even met his parents and introduced him to William and Harry.
While Hasnat eventually ended their romance, fearful of the media attention, he opened up about their relationship in court in 2008, saying, "I think in her head she wanted to get married, but practically she had not thought about the implications. . . . Emotionally she felt she was still young. She wanted a husband to be there for her, to have a normal relationship with him," he said.
