However, there have been a few instances where the members of the family have gone against conventions. In one such case, Queen Elizabeth, who is a firm follower of the royal rules, bent the guidelines for her then eight-year-old granddaughter Zara Phillips.
According to the reports, Zara wanted to attend Royal Ascot with her mother Princess Anne in 1989.
But the age limit for attending the mega event was 18 years.
However, the Queen then gave her permission to be a part of the event.
The eldest granddaughter of Queen Elizabeth II was the only child to have been allowed into Royal Ascot that year.
Since then, the age restrictions have changed, with children under the age of 18 allowed to attend Royal Ascot when accompanied by a paying adult.
Ascot Racecourse is a dual-purpose British racecourse, located in Ascot, Berkshire, which is used for thoroughbred horse racing.
It hosts 13 of Britain's 36 annual Flat Group 1 horse races and three Grade 1 Jumps races.
Zara, who attended the Royal Ascot, later turned out to be a British equestrian Olympian.
