A man convinced he is the love child of the Duke and Duchess of Cornwall claims Princess Diana knew of his existence before her death.
Simon Dorante-Day, 52, was born in Gosport, near Portsmouth, in April 1966, and was adopted at 18 months old by British couple Karen and David Day.
He now lives in Queensland, Australia, where he has spoken a number of times about his outlandish belief that he was placed for adoption by the then 18-year-old Camilla Shand. Prince Charles would have been 17 at the time Simon was conceived.
In a new interview with New Idea, Mr Dorante-Day explained he believes Princess Diana knew of his birth and that she had been preparing to ‘go public’ before her death in 1997.
He also recently shared a photo which he claims shows striking physical similarities between himself and members of the royal family.
He said: ‘At the time, there were all sorts of rumours flying around about the royal family, and my existence was one of them.
‘I think Diana was at a point where she was finding out answers about her life, how she was wronged, and she was going to go public with it.’
Mr Dorante-Day has a public Facebook page where he shares updates about his mission to be recognised as the Duke and Duchess of Cornwall’s son.
Part of his evidence is side-by-side comparison photos of his children with members of the Royal Family, which he claims reveal a striking similarity.
On a recent photo of Mr Dorante-Day as a young man, he wrote: ‘Good quality shot – the Camilla style Hair doesn’t miss.’
Another acquaintance noted how much he looked like a young Prince William, while others said he shared the Queen’s bone structure.
Mr Doronte-Day, whose middle name is Charles, writes on Facebook under the handle @PrinceSimonCharles.
He has said a number of times that he would like a DNA test to prove his family link.
The father-of-nine explained his adoptive grandparents formerly worked for the Queen and Duke of Edinburgh in the royal household and that they believed he was the Duke and Duchess of Cornwall’s child.
‘[My grandmother] didn’t just hint at it, she told me outright,’ Mr Doronte-Day said.
Prince Charles, who married Diana in 1981, and the Duchess of Cornwall have never commented on Mr Doronte-Day’s claims.
Clarence House has been contacted for comment.
