Mr Dorante-Day also took the opportunity to reshare a lengthy interview he did with Seven News on his plight to prove he is the son of the King.

Part of his claims is that there are varying reports over the ages of Charles and Camilla when they met – with Mr Dorante-Day claiming they met as teenagers, not in their early 20s.

‘I’m right, why hide the real date of when they first met? Unless there’s a reason!’ he said.

Mr Dorante-Day, who lives with his wife Elvie in Queensland, has done several interviews with media, explaining why he believes he is related to the King and Queen, including comparing physical attributes.

He also claims his kids share similar features to the children of Prince William and Kate.

He had said previously he is committed to pursuing legal action in an attempt to force the King into a paternity test.

Mr Dorante-Day’s case alleges King Charles and Queen Camilla began their close relationship in 1965, a year before his birth certificate says he was born.

However, Charles and Camilla are widely reported to have met at a polo match in Windsor Great Park in 1970.

Mr Dorante-Day insists that Camilla kept him until he was eight months old, hiding him from the world with the help of the royal family and protection officers, and claims to have been told it was a condition of the adoption that his names Simon and Charles were not changed.

The father-of-nine also referred to Queen Elizabeth II as his ‘grandmother’ at the time of her death.
