Simon enjoys posting pictures of himself to prove his likeness to the royals.

An Australian man who claims to be the secret son of King Charles III and Camilla has shared the latest twist in his royal paternity case in the wake of the Queen Elizabeth's death. Simon Dorante-Day, 56, has made headlines around the world with his 'findings', which he says are the result of years and years of research. The Queensland man says he’s been inundated with requests from media and royal watchers around the world in the days following the Queen’s passing last week, with many conspiracy theorist desperate to know what he does next - especially as a fortune teller has claimed that 'Charles will abdicate and a mystery heir will reign instead'.

"And secondly, Camilla and her family are certainly not above the law. So that argument’s already been had and settled." Earlier this year, the man also alleged that he penned a letter to the late Queen asking her to encourage her son to participate in DNA testing. However, the monarch didn't dignify the letter with a response. Simon has now said that despite the recent accession, it hasn’t slowed down his efforts in looking at the legalities of the case.

In his final ruling last time I was before the courts, the judge told me that if I come back with the evidence all nice and neatly stamped, then there’s no reason to deny an application for a DNA test, and Charles and Camilla will have to answer that." Simon has been claiming to be the son of Charles and Camilla for years, maintaining his adoptive grandmother told him on her deathbed, the Daily Mail reports. Last year, Simon also posted a montage of pictures including a snap of himself next to one of Prince William. His Facebook is littered with posts from Simon of him comparing himself to the royals, eager to point out how similar he looks to them. But Simon's pretty convinced and believes that he has been part of a major cover up to keep his identity secret as the illegitimate child of the Prince of Wales. According to Simon, he was conceived while the royal pair paid a trip to Australia in 1965, which means Charles and Camilla would have been teenagers despite meeting in 1970. However, Simon insists that they were secretly connected before then.

Again, this is all according to the 56-year-old engineer. Both of Simon’s adoptive grandparents worked for the Queen and Prince Philip at one of their royal estates, which he says led the couple to take him in and raise him as their own. As bonkers as this sounds, only time will tell...
