Prince William was not his mother’s first child: that he has a ‘secret sister’, now 33, called Sarah and living incognito in a small New England town in the United States.
In December 1980, Lady Diana Spencer, then a 19-year-old virgin, was ordered by the Queen to undergo gynaecological tests to establish that she was capable of bearing children before her engagement to the heir to the throne could be announced.
Diana’s eggs were harvested and fertilised with Prince Charles’s sperm. The tests proved successful, and the engagement of Charles and Diana was duly announced.
But one of the team who examined Diana, a ‘rogue doctor’, secretly held one of the embryos back and implanted it in his own wife. Unknown to her, she became the surrogate mother of the biological child of Charles and Diana.
Sarah is reported as claiming that as she was growing up, she was always being told that she was ‘a dead ringer’ for Diana. Then, in her late 20s, her parents were both killed in a car accident. After their deaths, she came across a diary which revealed that she was the product of a donated embryo and of in vitro fertilisation (IVF).
Sarah says that she attempted to trace the origin of the donated embryo to find out who she really was. But about two years ago, a menacing message was left on her answer-phone, warning her to stop looking if she valued her life.
Terrified by the thought that her life might be in danger, and haunted by suggestions that Diana’s death in Paris was not an accident but murder, she emigrated to America, where she now lives under a secret identity.
The Palace had battled to keep all this under wraps for decades.
Prince William’s pregnant wife Kate carried out a top-secret mission while in New York — quietly meeting with a woman Palace insiders believe is Diana’s secret daughter’.
This was the real reason for the couple’s trip to The Big Apple. The other events were just a cover. William wants to know the truth.’
