The Royal family are preparing for the first Trooping the Colour since King Charles took the throne.
But despite being an age-old tradition, one royal expert expects the event to be extremely different from the past.
According to Gareth Russell, it will be a 'slightly spectacular version of it'.
He continued: "The first one of a new reign is a bit punchier and has a higher production value. We know that all seven of the regiments will be there, and this is more than we’re used to seeing."
The Trooping the Colour will take place on Saturday, June 17 and celebrates the official birthday of the sovereign, reports US Magazine.
The traditional parade dates back to the reign of King Charles II, who served from 1660 to 1685.
And to celebrate the new monarch's birthday - which isn't actually until November 14 - King Charles has planned to revive a tradition that hasn’t been seen for nearly 30 years.
The monarch will ride on horseback during the parade, marking the first time a royal has saddled up at the event since 1986 when Queen Elizabeth II rode one of her beloved horses for the procession.
In her later years, the monarch, who died in September 2022, took the salute from a carriage.
The author of Do Let’s Have Another Drink!: The Dry Wit and Fizzy Life of Queen Elizabeth the Queen Mother, Gareth Russell said: "It’s a big event regardless of the scale of it, but because this is the first of Charles III’s reign, we are seeing more soldiers involved.
"[Charles] certainly wanted to take the salute from horseback. It matches the tone of the inaugural, for want of a better word, Trooping of the Colour for his reign."
Prince William is also likely to have a different role in the ceremony after he inherited his father's previous title.
The Duke of Cambridge, 40, became the Prince of Wales after his grandmother’s death, with Kate taking the Princess of Wales title.
“There is a very keen determination to present him as the next in line." Gareth explained.
“I think … he’ll have moved up. He essentially will be occupying the place that his father occupied at these [events] under the reign of Elizabeth II.”
Earlier in June, William attended the rehearsals for the historic parade, where two of the guards fainted due to the heat.
After the incident made headlines, the Duke of Cornwall publicly shared his gratitude for their service.
“A big thank you to every soldier who took part in the Colonel’s Review this morning in the heat,” William tweeted on Saturday, June 10.
“Difficult conditions but you all did a really good job. Thank you.”
