Simon Dorante-Day – Australian’s Royal Paternity Claim

James Edward Carter Davies • 2026-03-16 • Reviewed by Daniel Mercer

Simon Charles Dorante-Day has spent over three decades arguing that he is the secret son of King Charles III and Queen Camilla. The 58-year-old Australian asserts that he was born in 1966 from a teenage relationship between Charles, then 17, and Camilla, then 18—years before their officially documented romance began.

Dorante-Day’s allegations have persisted since the 1990s, gaining renewed attention in 2024 with threats of fresh legal action. He points to family testimony, disputed hospital records, and physical resemblances as evidence, while Buckingham Palace has maintained complete silence on the matter.

The claims represent one of the most persistent unsolicited royal paternity challenges in recent decades, raising questions about adoption records, DNA verification, and the boundaries of royal privacy.

What is Simon Dorante-Day’s Claim Against King Charles and Camilla?

The Alleged Teenage Relationship

Dorante-Day maintains that Charles and Camilla conceived him in 1965 when the future King was 17 and Camilla was 18. This timeline would place their relationship five years before historical records indicate they first met. Official biographies state the pair were introduced in 1970, creating a fundamental chronological conflict with Dorante-Day’s narrative.

He alleges that Camilla disappeared from Britain’s social scene for at least nine months preceding his 1966 birth, while Charles was reportedly sent to Australia during the same period—a separation he interprets as evidence of a cover-up.

The Adoption Arrangement

According to Dorante-Day, his adoptive grandmother told him “outright” on multiple occasions that he was the biological child of Charles and Camilla. He claims his first and middle names were preserved as “Simon Charles” as a condition of adoption, noting that Charles and Camilla had a close friend named Simon during that era.

Timeline Discrepancy

Historical records indicate King Charles and Queen Camilla did not meet until 1970. Dorante-Day’s claim requires a five-year adjustment to established royal biographies, which historians have not substantiated.

What Evidence Supports or Debunks Simon Dorante-Day’s Royal Claim?

Family Testimony and Childhood Memories

Dorante-Day cites his adoptive grandmother’s repeated assertions as primary evidence. Additionally, he recalls being taken to specific houses around Portsmouth during childhood where he spent time with a woman he believes was Camilla, while protection officers and his adoptive parents waited outside. These memories remain unverified by independent sources.

Documentary Anomalies

A historian reviewing Dorante-Day’s birth certificate allegedly determined that the listed hospital delivered no babies during the 1960s and that the named birth parents were “fictitious.” These claims, if accurate, would suggest irregularities in his adoption documentation, though no court has verified these assertions.

Visual Comparisons

Dorante-Day has published numerous side-by-side photographs comparing his facial features to King Charles, Prince William, and Prince Harry, asserting he bears closer resemblance to the King than his acknowledged sons possess. He has also shared images of his daughter Meriam alongside Princess Charlotte, drawing parallels in appearance. These comparisons rely on subjective interpretation rather than genetic evidence.

Unverified Documentation

Assertions regarding falsified hospital records and fictitious parent names remain unproven in legal proceedings. The hospital in question has not issued public statements confirming or denying these specific claims.

The DNA Question

No DNA testing has occurred between Dorante-Day and the royal family. He has proposed a “four-way paternity test” involving himself, Camilla, Charles, and his adoptive father to establish biological relationships definitively. The royal family has not responded to these requests.

What is Simon Dorante-Day’s Current Legal Status?

In 2018, Dorante-Day attempted to file a motion in Australia’s Family Court to compel a meeting with Charles and Camilla during their Commonwealth Games visit, seeking to facilitate DNA testing. The court did not grant the application.

As of late 2024, he confirmed plans for a “new court battle” should the royal couple proceed with their scheduled October 2024 Australian tour. He has stated his intention to pursue legal avenues to force DNA testing, though specific filings remain undisclosed.

Proposed Testing Method

Dorante-Day advocates for a four-way paternity test, which analyzes genetic markers against both potential biological parents and the subject. This method can exclude paternity with near certainty but requires voluntary participation from all parties.

What Remains Proven Versus Speculative?

Established Information Information That Remains Unclear
Dorante-Day was born in 1966 and adopted in Portsmouth at eight months old The identity of his biological parents
His adoptive grandmother worked for Queen Elizabeth II’s household Whether Charles and Camilla met before 1970
He has filed multiple unsuccessful legal motions for DNA testing The accuracy of his birth certificate documentation
Buckingham Palace has maintained complete silence on his claims The significance of his childhood memories
He currently resides in Australia with his family Whether DNA testing will ever occur

Historical Context of Unsolicited Royal Paternity Claims

Unsolicited claims of royal parentage are not unprecedented in British history. Throughout the 20th and 21st centuries, various individuals have asserted biological connections to the House of Windsor, often citing sealed adoption records or alleged secret relationships. These claims typically face insurmountable legal barriers, as the royal family maintains a strict policy of neither confirming nor denying such allegations, treating them as private matters without public comment.

The Dorante-Day case distinguishes itself through its persistence across three decades and its reliance on specific documentary challenges rather than purely circumstantial evidence. Like Kim Yo-jong – Kim Jong-un’s Sister and Key Political Figure, who operates within a deeply private and controlled institutional framework, Dorante-Day’s claims highlight the difficulty of penetrating established narratives about high-profile families where privacy and image management are paramount.

He has also claimed to have a “bond” with Prince Harry as fellow “black sheep of the royal family”, suggesting a psychological identification with ostracized royal figures rather than merely a biological claim.

What Have Dorante-Day and Palace Sources Actually Said?

“I’m 100 per cent confident that I will have the answers to this and the truth out there.”

— Simon Dorante-Day, 2024 interview with 7NEWS

“Charles and Camilla, Buckingham Palace, the entire royal family – not one of them has ever said my claims are not true. They’ve never denied what I believe, told me I’m wrong. And I think their silence speaks volumes.”

— Simon Dorante-Day, statement to Tyla

The royal family has maintained complete silence regarding Dorante-Day’s allegations, neither confirming nor explicitly denying his claims.

What is the Current Standing of These Allegations?

Simon Dorante-Day remains an Australian grandfather asserting unproven royal parentage based on disputed documents, family testimony, and visual comparisons. Despite three decades of legal challenges and media campaigns, no DNA testing has occurred, and Buckingham Palace has maintained its policy of silence. The allegations rest upon a fundamental contradiction with established historical timelines, leaving the claims unsubstantiated by verifiable evidence. As with complex financial examinations like the Jennifer Aniston Net Worth – $320 Million Breakdown 2024, separating documented fact from narrative requires careful scrutiny of primary sources—scrutiny that, in this case, has yet to yield definitive proof.
