A man who claims he is the lovechild of King Charles and Queen Consort Camilla has threatened to bring legal action to prove his heritage.

He also said that it is a ‘kick in the face’ to see Prince William named as the new Prince of Wales.

56-year-old Simon Charles Dorante-Day was eight months old when he was adopted and insisted that his adoptive grandmother revealed that he was the ‘secret son’ of Charles and Camilla.

For years, Simon has asked the royal couple to undergo a DNA test to prove his genetic heritage. He has also sought senior legal advice after a letter written to the late monarch was dismissed.

Speaking to News7, Mr. Dorante-Day said: “It’s hard not to take Charles naming William as the Prince of Wales as anything other than a kick in the face.

“I don’t want to feel that way, but I do. I just think, the least Charles can do is give me an answer – acknowledge me. He gives William a title like that, well where’s my answer? Where’s my DNA test? If you are not my father, then prove you’re not.”

Mr. Dorante-Day, whose adoptive grandparents had worked for the Queen and Prince Philip, also said that he will pursue legal action to force the new monarch into a paternity test.

He explained that there has been a discussion between him and a judge and his barrister about the legal standing of the King and whether he is protected by the law or above the law.

“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,” he added.

Mr. Dorante-Day alleges Charles and Camilla started their close relationship in 1965 – one year before he was born.

He insisted that the Queen Consort kept him until he was 8 months old until it was arranged for the daughter of a royal household staff member to take him under her care.

The 56-year-old also believes inconsistencies on his birth certificate prove that he has royal blood.
