Two activists from the anti-monarchy campaign group Republic bought tickets to the public opening of Buckingham Palace's State Rooms, broke away from the tour, and unfurled a large banner in the throne room depicting Prince Andrew and Jeffrey Epstein walking together through Central Park. The banner carried a single question: "What did you know?"
The stunt, carried out on a Monday during the palace's summer opening, marks one of the most brazen activist breaches of a royal residence in recent memory. It raises immediate questions about security at a building that has absorbed £369 million in taxpayer-funded refurbishments over nearly a decade, and about the monarchy's ability to keep the Epstein scandal contained.
Republic's spokesperson Graham Smith framed the action as a direct challenge to King Charles and Prince William.
"Republic activists have taken questions about Andrew to the heart of the royal household, the symbolic home of the monarchy."
The two unnamed activists purchased standard tickets to the palace's public opening of the State Rooms, then separated from the group and made their way to the throne room. There they set up the banner, a photograph of Andrew and Epstein on their now-infamous 2010 Central Park stroll, overlaid with the words "What did you know?"
No arrests, injuries, or other consequences were reported. That silence itself is striking. The palace has not disclosed how long the banner remained displayed, how security responded, or what steps will be taken to prevent similar incidents.
The breach follows a pattern of activist stunts targeting high-profile British institutions. In 2021, Extinction Rebellion dumped seven tonnes of horse manure outside the Daily Mail headquarters and spray-painted the News Corp building in London, resulting in 23 arrests. Republic's palace action, by contrast, appears to have produced no immediate law enforcement consequences at all.
The banner's question, "What did you know?", is aimed squarely at the senior royals.
"This question isn't going away. It is simply not believable to think that Charles and William weren't briefed years ago about the numerous allegations against Andrew."
Smith went further, arguing that security services, police, and the government would have flagged Andrew's behavior to the palace years ago, "not least because of the potential threat to national security and the risk of blackmail."
Republic is also pursuing what it describes as a possible private prosecution of Andrew. Green MP Sian Berry is reportedly planning to raise the issue of royal secrecy in Parliament, calling for an end to the royal family's exemption from freedom of information rules.
Smith was blunt about the group's broader aims.
"Republic will not rest until these questions are answered, the protests will not stop until the monarchy is gone. The monarchy survives on secrecy, and that secrecy has to stop."
The throne room protest lands at a moment when the Andrew situation has already spiraled well beyond the palace's control. Andrew was arrested on February 19, his 66th birthday, on suspicion of misconduct in a public office in connection with his dealings with Epstein. Police questioned him for 12 hours.
Ten days before the arrest, King Charles expressed what was described as "profound concern" over the accusations his brother faced and said Buckingham Palace was "ready to support" police in any investigations. The King then expedited Andrew's eviction from Royal Lodge, a seven-bedroom, 30-room mansion in Windsor.
Andrew left Royal Lodge on February 2, moving under cover of darkness to Wood Farm on the Royal Sandringham Estate in Norfolk. By April, he had relocated again to Marsh Farm on the Sandringham Estate, which had been refurbished with a tall fence and upgraded security.
An unnamed palace source offered a revealing summary of the King's thinking.
"The King feels he has no other option than to provide for his brother, who will be privately funded on a private estate. Every time he's tried to support himself by independent means, it has led to greater trouble. Containing him is the hope."
"Containing him", a striking admission from inside the institution.
The files that accelerated Andrew's downfall contain material that extends well beyond the prince himself. Emails appeared to show Andrew passing on secret details of investment opportunities to Epstein following visits to Singapore, Hong Kong, and Vietnam in 2010 and 2011. The source's own language, "appeared to show", signals that this characterization has not been independently confirmed.
The files also pulled Andrew's ex-wife Sarah Ferguson into the spotlight. Emails suggest Epstein had been bankrolling Ferguson for 15 years. A 2009 email attributed to Ferguson reads: "I urgently need 20,000 pounds ($27,521) for rent today. The landlord has threatened to go to the newspapers if I don't pay. Any brainwaves?"
Another email attributed to her contained the words "Just marry me," directed at Epstein.
The files also referenced Ferguson apparently discussing then-19-year-old Princess Eugenie in 2010, and described Ferguson as having introduced her then-22-year-old goddaughter to Epstein after his release from prison. Ferguson has been very rarely seen in public since the scandal deepened, breaking cover after 213 days at a ski resort in Austria in April.
The most high-profile accusation came from Virginia Giuffre, who accused Andrew of having sex with her three times when she was 17 years old in 2001. Giuffre said she was coerced into sexual dealings with Andrew by Epstein and Ghislaine Maxwell. The alleged encounters occurred at Maxwell's London home, Epstein's New York mansion, and Epstein's private island.
Giuffre died in April 2025 near her home in Australia. She was 41.
A separate allegation emerged in February of this year. An unidentified woman in her 20s, represented by lawyer Brad Edwards, alleged she was trafficked to the UK in 2010 by Epstein for a sexual encounter with Andrew at Royal Lodge. She further alleged she was subsequently taken to Buckingham Palace for tea and a private tour.
Andrew has repeatedly denied any wrongdoing. Police are reportedly preparing to interview victims of Epstein in the United States.
In a development that carries its own symbolism, the royal family announced in June that no British monarch would ever live permanently at Buckingham Palace again. King Charles and Camilla will reside at Clarence House, across The Mall from the palace.
Buckingham Palace will continue to serve as the monarchy's ceremonial headquarters, and, apparently, as a venue where activists can buy a ticket and unfurl a banner in the throne room challenging the institution's handling of a sex trafficking scandal.
The £369 million refurbishment, funded by taxpayers, has been ongoing for nearly a decade and is expected to be completed next year. What that money has purchased in the way of security remains an open question.
Andrew has been seen regularly taking drives from his Sandringham home. At the beginning of June, he was spotted in his Range Rover with a bruise on his face. No explanation for the bruise has been offered.
His daughters, Princesses Beatrice and Eugenie, were spotted together after lunch in London's Mayfair in May. Eugenie announced in May that she was expecting her third child with husband Jack Brooksbank, sharing a photo of their children Ernest and August looking at an ultrasound scan.
The family appears to be carrying on. The questions Republic is pressing, about what the senior royals knew, and when, remain unanswered.
Graham Smith's claim that "the monarchy survives on secrecy" may be overwrought as a general proposition. But on the specific matter of Andrew and Epstein, the palace's approach has been unmistakable: move Andrew out of sight, fund his living expenses privately, erect taller fences, and hope the public moves on.
That strategy depends on a compliant information environment. Republic and Sian Berry are now pushing to strip the royal family of its exemption from freedom of information rules, a reform that, if enacted, could force disclosure of internal palace communications about Andrew's conduct and the institution's response.
Epstein was convicted in 2008 of soliciting a prostitute and procuring a child for prostitution, serving 18 months. His connections to Andrew continued afterward, the Central Park photograph dates to 2010, well after Epstein's conviction. The investment-related emails span 2010 and 2011. The alleged trafficking of the unidentified woman to Royal Lodge is said to have occurred in 2010.
All of this happened after the world knew who Epstein was. That is the fact that makes the "What did you know?" question so difficult for the palace to dismiss.
When two people with standard-issue tickets can walk into the throne room and hang a banner asking questions the monarchy refuses to answer, the problem isn't the banner. It's the silence.
