A man who claims that he's the illegitimate son of Prince Charles and Camilla Parker-Bowles is using his own offspring as proof of his claim to the throne.
According to Indy100, Simon Dorante-Day, who was born in the United Kingdom but who now lives in Queensland, Australia, alleges that he is the eldest son of the Prince of Wales.
He captioned the post: "Uummmm an interesting comparison [sic]" in an attempt to goad viewers to notice a physical resemblance between his son and the Queen.
In a post recently made on his official Facebook page, the 55-year-old uploaded an image of his teenage son Liam, along with two images of Queen Elizabeth.
A number of commenters clearly agreed that Liam did look similar to the monarch.

Dorante-Day has repeatedly asserted that he is the victim of a conspiracy at the hands of the British royal family, claiming he was conceived in 1966 when Prince Charles was 17 and Parker-Bowles was 18.
A adopted by a family from Portsmouth, England, who had links to the British Royal Family, he was allegedly told by his adoptive grandmother that he was Charles' son at a young age.
Speaking in a previous interview with 7NEWS.com.au, Dorante-Day claimed that he often comes across new comparison photos between himself and the royals.
He told the above publication: "All the royal fans and supporters who send them to me, they’re amazing. And I really think it’s like an Agatha Christie novel for them, where they’re looking for clues and searching for answers.
"There are so many people invested in my story now and helping me, it’s really amazing. But at the end of the day, it would be really nice to wake up in the morning and not have to look for evidence and keep defending it."
