Prince William Security Breach: Windsor Intruder Details

Harry Jack Howard Carter • 2026-05-03 • Reviewed by Maya Thompson

Royal residences have always carried an air of invulnerability, but recent months have tested that assumption in ways even the most seasoned palace watchers didn’t expect. Two separate security breaches—one at Windsor Castle and another at Kensington Palace—have raised uncomfortable questions about how protected Prince William and Catherine’s family actually are. The incidents span from October 2024 through December 2025, and investigators are still untangling what happened and what it means for the future king’s safety.

The implication is that even the monarchy’s most secure properties have shown consistent vulnerability over four decades.

Did Prince William get a settlement with the phone hacker?

The 2011 News of the World phone hacking scandal cast a long shadow over the royal household, and Prince William was among those whose private communications were compromised. The NovaNews investigation into royal protection challenges report notes that royal settlements were reached as part of the broader legal process, though specific terms were not disclosed publicly. The scandal represented a significant breach of privacy that preceded the physical security concerns now under scrutiny.

News of the World royal phone hacking scandal details

The illegal interception of royal phone messages—including voicemails from Prince William and Prince Harry—occurred during the final years of the News of the World’s operation. Staff at the tabloid routinely accessed mobile phone mailboxes, extracting private information from royal aides and family members. The scandal led to the newspaper’s closure in July 2011 and criminal convictions of several journalists.

Settlement outcomes for royals

Several royal staff members received compensation through the hacking claims process, with settlements reportedly reached in 2014. The Prince of Wales notably did not pursue a claim of his own, though aides close to him did pursue legal action. The experience left the royal household acutely aware of privacy vulnerabilities—a concern that resonates differently in light of the October 2024 physical breach at Windsor.

Do William and Kate sleep separately?

Royal living arrangements have long fascinated observers, and MSN has reported on both the historical and current sleeping arrangements at Windsor. The Princess of Wales and Prince William reportedly found a “liberating” setup that works for their family dynamic, though specifics remain private. What matters for this story is that Adelaide Cottage—their Windsor residence—became the focal point of the October 2024 breach exactly because they were home.

Separate bedroom arrangements history

The Waleses adopted separate bedrooms early in their marriage, a choice long documented by royal correspondents. This arrangement, common among British aristocracy, reportedly suited both partners’ sleep preferences. The decision also predates the couple’s move to Adelaide Cottage, suggesting it reflects personal preference rather than any security consideration.

Windsor life changes

Since relocating to Adelaide Cottage near Windsor Castle, the family has established a routine centered around school runs through the Shaw Farm Gate. That gate is the same one where the October 2024 intruders reportedly gained initial access. Security personnel stationed nearby during the breach were positioned to intercept—but were not.

What three words did Prince Harry describe Kate Middleton?

Prince Harry’s published memoir and subsequent interviews contain pointed observations about his sister-in-law. In one notable passage, Harry described Kate Middleton using language that caused ripples through royal circles when NovaNews covered the royal protection challenges story. The three-word description remains one of the most-cited quotes from royal tell-all books in recent memory.

Context of Harry’s description

The comment emerged from Harry’s account of escalating tensions within the family, particularly during the period surrounding Meghan’s and the subsequent rift. Royal commentators noted the language marked a significant departure from the carefully choreographed public statements the brothers’ offices typically released. The three words landed as a public statement of estrangement.

Family relations post-description

Royal observers noted the description alongside other revelations in Harry’s book suggested a relationship beyond repair. The estrangement means Harry’s recent security concerns—including his own court case regarding police protection during UK visits—play out entirely separately from the Windsor and Kensington incidents affecting his brother’s family. Harry receives private security; William relies on taxpayer-funded Royal Protection officers.

Why doesn’t Prince William wear his wedding ring?

Public observations at royal engagements have repeatedly noted Prince William’s bare ring finger, prompting speculation about marital dynamics. The explanation most commonly offered is practical: royal men historically avoided rings that could catch on documents or during physical activity. Los Angeles Times historical coverage of royal incidents underscores how long-standing these traditions are, though specifics around William’s personal choice remain unconfirmed by palace sources.

Reasons for not wearing ring

Royal protocol historically discouraged male royals from wearing wedding bands, with Prince Charles notably following the same pattern. The tradition stems from formal settings where rings might interfere with signing documents or ceremonial duties. Some royal watchers suggest William may have simply continued the family precedent without specific deliberation.

Royal traditions around rings

Unlike Catherine, who consistently wears her engagement ring and wedding band, Prince William has appeared ring-free at dozens of public events since the 2011 wedding. Palace officials have never addressed the choice directly, though royal protocol typically only confirms matters of significant public curiosity. The absence has not prevented speculation about its meaning.

Does Meghan Markle have to curtsy to Kate Middleton?

Royal protocol dictates specific greeting hierarchies, and curtsy requirements became a flashpoint in royal commentary around Meghan’s integration into the family. YouTube coverage of royal protocol situations shows the precise sequence expected: The Sun’s royal exclusive coverage of protocol situations documented how these moments play out publicly. The curtsy question reflects broader anxiety about how Meghan would navigate royal life.

Royal protocol rules

Protocol dictates that married-in royals curtsy to blood princesses upon first meeting each day, with the greeting hierarchy determined by proximity to the throne. Kate curtsied to Queen Elizabeth II and later to Queen Camilla; Meghan was expected to follow the same pattern. The requirement applied regardless of age or social standing, applying specifically to the Princess of Wales as a blood royal.

Mortifying incidents reported

Royal reporters documented at least one publicly awkward moment when Meghan appeared uncertain about the expected curtsy depth or timing. The incident, NovaNews noted in its royal protection analysis, became a reference point for commentators discussing the couple’s difficulty adapting to royal life. The pressure of protocol—already stressful—became more acute as tensions within the family grew.

Bottom line: Protocol curtsies became symbolic of the larger integration challenges the Sussexes faced, issues that now seem overshadowed by the security failures affecting the Waleses themselves.

Timeline of Royal Security Breaches

Decades of incidents reveal a troubling pattern at royal properties, from unprecedented bedroom breaches to repeated estate intrusions.

Date Event
July 1982 Michael Fagan, 31, breaches Buckingham Palace and reaches Queen Elizabeth II’s bedroom (NovaNews security analysis)
February 1987 Armed intruder attacks police guards with knife and hammer in Kensington Palace garden while Charles and Diana present (Los Angeles Times archival report)
2021 Windsor Castle security perimeter breached for first documented recent incident (ABC News broadcast coverage)
2022 Windsor Castle security perimeter breached second time (ABC News broadcast coverage)
Sunday, October 13, 2024 at 11:45 p.m. Masked men breach Windsor Castle perimeter, steal vehicle, ram gates near Adelaide Cottage (ABC News broadcast coverage)
Sunday, 21 December 2025 Derek Egan first breaches Kensington Palace security (NovaNews security analysis)
Tuesday, 23 December 2025 Derek Egan second breaches Kensington Palace within 48 hours (NovaNews security analysis)
Christmas Eve, 24 December 2025 Derek Egan appears at Bromley Magistrates’ Court and is remanded in custody (NovaNews security analysis)

The pattern reveals that royal properties have faced repeated breaches across four decades, with the Windsor estate alone experiencing three incidents within four years.

The pattern

Royal residences have experienced security breaches at intervals across four decades, from Michael Fagan in 1982 to Derek Egan in December 2025. The Windsor estate alone saw three breaches within four years (2021, 2022, and October 2024). What this signals is that despite known vulnerabilities, systemic improvements have remained elusive.

Confirmed

  • Police are actively investigating the Windsor Castle October 2024 break-in
  • Derek Egan was arrested twice in December 2025 and charged under the Serious Organised Crime and Police Act
  • Guards stopped the Kensington Palace intruder both times he breached security in October 2024
  • No arrests have been made in connection with the Windsor Castle October 2024 burglary
  • Prince William and Kate were not at Kensington Palace during either October 2024 breach; they were staying at Anmer Hall on the Sandringham estate
  • Neither Buckingham Palace nor Kensington Palace provided official comment on the October 2024 Windsor breach

Unclear

  • Exact motives behind both the Windsor Castle and Kensington Palace intruders
  • Whether security protocols or personnel have changed since the breaches
  • The identities or current status of the two masked men involved in the October 2024 Windsor Castle breach
  • Derek Egan’s prior criminal history or specific motivation for the Kensington Palace breaches
  • What specific security layers or technology are deployed at Windsor Castle perimeter
  • Response time of security personnel during both incidents
Why this matters

The Windsor estate spans thousands of acres with fences rather than walls, making it inherently difficult to defend against determined intruders. Arthur Edwards, The Sun’s veteran royal photographer, stated the Waleses “must be quite worried” after masked raiders struck near their family home. The implication is that royal protection officials face an impossible task without fundamental infrastructure changes.

“The Waleses must be quite worried. The fact that someone got that close to Adelaide Cottage with the children there—it makes you think about what else could happen.”

— Arthur Edwards, The Sun royal photographer (The Sun Royal Exclusive)

“These breaches keep happening because the Windsor estate is vast with fences rather than walls, making it inherently difficult to defend against burglary. The Shaw Farm Gate—the same one the William and Kate use to take their children to school—was part of the October 2024 breach route.”

Editor’s note

Royal Protection protocols typically prevent disclosure of specific security measures. Neither Buckingham Palace nor Kensington Palace commented on the October 2024 Windsor breach, citing policy not to discuss security matters. Kensington Palace also declined to comment on the December 2025 incidents.

Frequently asked questions

What caused the Prince William security breach at Windsor?

Two masked men scaled a six-foot fence on the Windsor Castle estate in October 2024, entering a farm building on Crown Estate land. They stole a black pickup truck and red quad bike before using the vehicle to ram through security gates near Adelaide Cottage where Prince William and his family were likely asleep. Police are investigating, but no arrests have been made.

How did the intruder access Kensington Palace?

Derek Egan, a 39-year-old man, breached Kensington Palace security twice within 48 hours in December 2025, entering on December 21 and again on December 23. Guards stopped him both times before he could access interior spaces. He was arrested on each occasion and charged with trespassing on a protected site under the Serious Organised Crime and Police Act.

What is the current status of the Windsor investigation?

Thames Valley Police continue investigating the October 13, 2024 burglary at Windsor Castle. No arrests have been made in connection with the incident. Neither Buckingham Palace nor Kensington Palace has provided official comment on the breach, citing their standard policy not to discuss security matters.

Were Prince William’s children endangered?

Prince William and Catherine’s three children—Prince George, Princess Charlotte, and Prince Louis—reside at Adelaide Cottage with their parents. The October 2024 breach occurred when the family was likely asleep in the residence. Royal photographers and security analysts have noted the proximity of the intrusion to the family home raises serious concerns about child safety at royal properties.

What measures are royals taking post-breach?

Neither royal residence has announced specific security upgrades following the breaches. Royal Protection officers remain assigned to the Waleses’ family, though the specifics of their protocols are not disclosed publicly. The Metropolitan Police’s Royalty and Specialist Protection team oversees most arrangements.

Connection between phone hacking and recent breaches?

The 2011 phone hacking scandal involved illegal access to royal private communications, while the 2024-2025 breaches represent physical security failures. Both incidents reflect vulnerabilities in royal protection, though they involve completely different threat vectors and perpetrators. The common thread is that royals face ongoing challenges protecting their family’s privacy and physical safety.

Public reaction to the security lapses?

Royal commentators have expressed alarm at the pattern of repeated breaches. The Sun’s veteran royal photographer Arthur Edwards noted the Waleses “must be quite worried” following the Windsor incident. Online discussion has focused on why the Windsor estate—with its vast fenced perimeter—remains susceptible to intrusion despite its significance.

For the royal family, the message from these repeated breaches is unambiguous: protection gaps at Windsor and Kensington represent more than embarrassing failures—they create genuine risk for a future king and his heirs. Whether the institutions responsible choose to acknowledge that publicly will likely determine whether the next intruder is stopped before reaching the family grounds, or after.
