Princess Beatrice and Princess Eugenie have the chance to show "loyalty to King Charles", a PR expert has claimed.
The York sisters have not confirmed whether or not they will attend Trooping the Colour this weekend, a parade to celebrate the monarch's birthday.
The princesses would always attend the parade growing up, and even as young adults up to the year 2019.
However, ever since their father, Prince Andrew, stepped down as a working royal five years ago, the sisters have not appeared on the Buckingham Palace balcony.
During Queen Elizabeth II's Platinum Jubilee, the late monarch decided that only working members of the Royal Family could appear on the iconic landmark.
This meant Princess Beatrice, 35, and Princess Eugenie, 34, were barred, as well as their cousin Prince Harry and their father, the Duke of York.
Emma Starrs, a PR expert from Kenland Media Relations, spoke exclusively to GB News to explain why it would be a positive move to allow the York sisters to attend Trooping the Colour on Saturday.
She said: "Trooping the Colour will be seen as a celebration of times to come, as well as being the monarch’s birthday parade.
"Therefore, with eyes on the future, Beatrice and Eugenie would be a positive addition to the balcony.
"As dutiful granddaughters of the late Queen, their appearance would show loyalty to her legacy and to King Charles, which comes above all else.
"It's a tradition they've grown up with, have fond memories of and they'll understand the cultural importance of this event."
On Friday, it was confirmed by Kensington Palace that Princess Kate, 42, would attend Trooping the Colour.
LATEST ROYAL UPDATES:
The Princess of Wales has been battling cancer and undergoing chemotherapy away from the public eye.
Starrs added: "Kate’s appearance on the balcony is incredibly welcome.
"There will be cheering along The Mall and around the world by millions who have been concerned for her health and missing her presence at royal events.
"It is uplifting, reassuring and a sign that the health woes that have blighted the Royal Family are diminishing. It is very brave of her, as royal watchers will be looking for clues on the state of her health, but it is an amazing achievement."
