Royal security services are on high alert this weekend to protect King Charles and Queen Camilla from an Australian who claims to be their secret love child.
British-born Simon Charles Dorante-Day, 58, is convinced he is their illegitimate son, who was given up for adoption shortly after birth and taken in by Royal Palace staff.
He has been demanding a DNA test to prove his claim for years, but has now been placed on a protection list after a warning that he could take matters into his own hands.
When Charles and Camilla’s tour was announced, Mr Dorante-Day hinted at a plan to confront the royal couple after they arrived in Sydney on Friday night.
“What am I going to do this time?” Mr Dorante-Day said in May.
“Well, it would be very foolish not to take action if he ends up in the same jurisdiction as me.
“But I think it would be even more foolish if I showed my cards prematurely.”
Now, close protection experts have confirmed that the Australian is being closely watched by royal bodyguards while the king and queen are in the country.
Royal security services are on high alert in Sydney this weekend to protect King Charles and Queen Camilla from an Australian who claims to be their secret love child.
British-born Simon Charles Dorante-Day, 58, is convinced he is their illegitimate son, who was given up for adoption shortly after birth and taken in by Royal Palace staff.
“There are probably 20 names on that watchlist already,” a security expert – who cannot be named for security reasons – told Daily Mail Australia.
“And anyone who makes noise in public is certainly going to be of great interest.
“Background checks have already been done on the names they have and it is standard practice to do psychological evaluations based on any criminal convictions and social media.”
Mr Dorante-Day was adopted in August 1966 when he was about eight months old in Portsmouth on the south coast of England, when Camilla would have been 18 and Charles 17.
The father of nine claims his adopted grandmother, who worked for the Queen, helped arrange the move and his new life as a royal outcast.
He now wants the truth to come out so he can take William’s place as heir to the British throne and become the new Prince of Wales.

Simon Dorante-Day has hinted at a plan to confront the royal couple after they arrived in Sydney on Friday night.
But royal escorts are said to have alerted police and ASIO to keep him away from Charles and Camilla while he is in Australia.
The royal couple land in Sydney on Friday night, where they will spend the weekend before heading to Canberra on Monday, before returning to Sydney before leaving Australia on Wednesday.
The Royal Protection Squad will be tasked with keeping Mr Dorante-Day away from both of them during the trip.
“The police have the authority to alert anyone they feel is necessary,” said the nanny with 30 years’ experience protecting high-profile dignitaries.
“The psychological brief would have determined whether that was necessary at all.
“They take everything into account, including any grudges the person may have against them, and also look out for irritable behaviour.”
Mr Dorante-Day has spoken of his frustration after years of publicly and privately pleading with the Royals to recognise his place in their family.
He refused to attend the King’s coronation in 2023, saying he had “better things to do”.
He added at the time: “You know the truth – and you stand there and accept the name King, knowing that you know the truth.”

His timeline of events contradicts the official history of the royal couple’s romance, which states that Charles did not meet Camilla until years after Mr Dorante-Day was born.
Mr Dorante-Day believes that inconsistencies on his official birth certificate and in his name prove that he is of royal blood.
But his timeline of events contradicts the official history of the royal couple’s romance, which states that Charles did not meet Camilla until years after Mr Dorante-Day was born.
Mr Dorante-Day claimed that his research shows that Charles and Camilla first became close in 1965, when they met at Winston Churchill’s funeral in January of that year.
However, it is widely reported that Charles and Camilla first met at a polo match in Windsor Great Park in 1970.
Camilla is said to have introduced herself with a reference to Edward VII and his mistress, Alice Keppel.
“You know sir, my great grandmother was your great grandfather’s mistress – what do you think of that?” she is said to have told him.
She eventually married Charles in 2005, a decade after her divorce from Andrew Parker Bowles in 1995.
Mr Dorante-Day has amassed 29,000 fans on Facebook after attempting to prove his royal birthright – but many have decried his outrageous claim.
“Who else is waiting with bated breath for mum and dad to arrive on Friday,” one poster sarcastically wrote in a private Facebook group this week.
“I wonder how much this is going to cost the taxpayer to know where [Dorante-Day is] so they can’t disrupt the visit,” added another.
