**Princess Catherine Sparks Royal Tensions Wearing Largest Tiara at State Banquet**
*Dec. 19, 2025, Published 7:07 p.m. ET*
Princess Catherine has reportedly sparked significant tensions within the royal household after wearing her largest tiara to date at a recent state banquet. According to insiders speaking to RadarOnline.com, Queen Camilla was left seething over what she viewed as an “audacious power play.”
### The Oriental Circlet ‘Power Play’
The source of the controversy is the December 3, 2025, State Banquet at Windsor Castle, held to welcome German President Frank-Walter Steinmeier. At the event, Kate chose to wear the Oriental Circlet Tiara—a historic piece commissioned by Prince Albert for Queen Victoria in 1853, featuring 2,600 diamonds and rubies.
Traditionally known for more understated jewelry choices, the Princess of Wales’ decision to don such a striking headpiece was notable. This bold choice coincided with a week in which she took center stage at multiple high-profile engagements, including her annual *Together at Christmas* concert at Westminster Abbey on December 5.
### Sidelined in Her Own Home
Sources suggest that the tiara, combined with Kate’s poised hosting of the banquet and a festive photograph with Prince William, 43, contributed to Camilla, 78, feeling sidelined within the royal family dynamic.
One insider shared:
*”Camilla was reportedly furious that Kate wore the enormous tiara at the banquet. She viewed it as yet another obvious move by Kate to steal the spotlight.”*
The insider continued,
*”Kate and William are positioning themselves with a lot of authority, almost as if Buckingham Palace were theirs. Camilla considers this unacceptable and hasn’t hesitated to express her frustration to courtiers and senior royals.”*
### Succession Fears and Expanding Influence
Another palace insider revealed that Kate has been gradually taking on more responsibilities across royal duties. While she handles these roles gracefully in public, Camilla is said to be privately struggling with the shift in influence and authority.
This transition reportedly forces the Queen to confront the reality of the impending succession, as King Charles III, 77, continues his medical treatment. Observers note that the Waleses’ growing centrality within the monarchy is part of a broader strategy to ease the King’s workload.
In a historic move this year, Charles granted William and Kate the authority to issue Royal Warrants—a power Kate is the first Princess of Wales to hold in over 115 years.
### A ‘Brutal’ New Strategy
Tensions have also been fueled by recent high-profile family decisions, including the growing distance of former Prince Andrew, 65, from royal duties. A source described William’s approach to managing family scandals as “brutal” and highly strategic, increasing Camilla’s unease.
The source explained:
*”Camilla can see from how Kate and William have managed Andrew, Sarah, and the Sussexes that they are highly strategic. She’s been cautioned against provoking them.”*
### Camilla’s Resilience Amidst Friction
Despite the ongoing friction, Camilla remains “headstrong” and “thick-skinned,” carefully maintaining appearances while the King continues to delegate more authority to the future Queen Catherine.
As the royal landscape evolves, all eyes remain on how the dynamics between these key figures will shape the future of the monarchy.
