In her final years on the throne, the late Queen started restricting the balcony appearance to only working royals, and for the most part, Charles has kept to this rule, although children of working royals could attend, with Lady Louise Windsor joining the family in 2024.
The York sisters weren't seen in public for the event

Given what has happened in the past year, it's not surprising that the York sisters weren't present at the celebrations. Although the royals aren't involved with the Epstein scandal that has embroiled their parents, it was recently revealed by a National Audit Office publication that they had been living in royal properties for below market-level rent.
Since stopping being a working royal, Andrew hasn't been seen for Trooping the Colour. Following further revelations about his friendship with convicted paedophile Jeffrey Epstein, Andrew was exiled from the royal family, now living in a property on the Sandringham Estate.
The Duke and Duchess have missed several successive Trooping events
Prince Harry and Meghan Markle
Since stepping back as working royals and moving to the United States, the Duke and Duchess of Sussex haven't attended Trooping the Colour, so it was no surprise that they weren't here this year. Harry is due to return to the country next month for his Invictus Games, so could a possible reconciliation be on the cards?
Both of the Duke and Duchess of Edinburgh's children were no shows for this year's Trooping the Colour. While Lady Louise had attended back in 2024, James has been absent for years. The two young royals are likely focusing on their studies, with Lady Louise missing Peter Phillips' wedding last week.
Peter was the main focus of the royal family last week, thanks to his marriage to Harriet Sperling, and the newlyweds opted against a balcony appearance.
While Mike has never made an appearance at Trooping the Colour, Zara has joined her mum, Princess Anne, in the past. But on this occasion, the former Olympic athlete didn't join her family.
While the Duke of Kent was seen standing alongside King Charles and other royals during Trooping, his younger siblings ended up skipping the festivities.
Embarrassing uncles are a staple of British weddings, but the ex-Duke of York's attendance at Peter Phillips's marriage to Harriet Sperling would have been a painful distraction
