Simon was born on April 5, 1966, in Gosport, Portsmouth, and was adopted by a couple named Karen and David Day. His adoptive grandparents Winifred and Ernest Bowlden both worked in the royal household of Queen Elizabeth and Prince Philip, According to 7NEWS.

He went on to tell 7NEWS, that his adoptive grandmother dropped a bombshell by telling him his real parents were Prince Charles and Camilla. “She didn’t just hint at it, she told me outright.”

Charles and Camilla’s relationship can be traced way back to the 1960s even before they got married in 2005. Charles continued seeing Camilla while staying married to Diana and that was one of the reasons their marriage ended.

Simon claims that he was conceived by the couple when they were teenagers, and the royal family covered it up to avoid a scandal and arranged an adoption under fake names. While the royals have refused to acknowledge his claims, he’s spent decades trying to prove his case.

“Can people conceptualize things, please? It’s not just about images and looking like them alone. It’s also about memories, events, people, and places! What Nanan told me, what Grandad told me, and what my adopted mother told me!… he posted on his Instagram page.

People soon started comparing a picture of him and Charles and were quick enough to spot the uncanny resemblance between the two.

Simon has been in the dark for years, but after the Queen’s death, he knew he couldn’t stay there any longer.

He told 7NEWS, The Queen’s death was a moment of complex emotions for Simon. He was sad over the Queen’s passing, but also sad that she never responded to his letters, and that a “window of opportunity has closed.”

Simon plans on taking the King to court and demanding a DNA test.

“There has been a discussion in there between a judge and myself and his barrister about the legal standing of Charles, and whether the monarch is protected by the law or is above the law,” Simon said. “And the answer to that was no – they told me that we don’t see any reason why he is. And secondly, Camilla and her family are certainly not above the law. So that argument’s already been had and settled.

If he presents his evidence in court then his application for the DNA test will have no reason to be rejected.

Simon also feels that his possible half-brother Williams is taking his place as the next line to the throne.

“I feel dismissed. Charles got what he wanted: he got the throne, he got his wife, he got it all. I don’t even get the truth about my mother. When’s it going to swing the other way? Now it’s time for me to get my happy ending.”
