When Prince William watches on as his father King Charles is crowned, it will be an insight into what his future holds when he one day takes the throne.
But the Prince of Wales won't just be a spectator for the historic celebration on May 6, he's expected to have a number of vital roles in the ceremony.
While Buckingham Palace is yet to officially confirm which royals will be doing what, royal expert and historian Tessa Dunlop has shared her best educated guess about what the day could look like.
She tells The Mirror: "Prince William and his off spring are next in line to the throne and coronations deliberately emphasise the order of precedence and succession. Like it or not this state occasion is all about royal hierarchy.

"Visual messaging through both costume and carriage will remind us who the future King and Queen are - whether the Sussexes like it or not."
As part of his plans to strip the ceremony back, it's understood that Charles has scrapped part of the Coronation which sees royals dukes keeling and paying homage to him. Traditionally they would also touch the crown and kiss the monarch's right cheek.
However William, as heir to the throne, will still do this but he will be the only one.
Tessa believes that the Wales family will "stand out" during the event, so will have very different roles to Prince Harry and Meghan Markle if they do decide to attend.
The adds: "In 1953 the Queen’s sister Princess Margaret had her own coronation gown designed by Norman Hartnell, embroidered with roses and daisies and offset with a stunning Cartier tiara.
"She travelled to the Abbey with the Queen Mother and they sat in a box overlooking proceedings with a four-year-old Prince Charles squashed between them.
"A similar scenario for the Princess of Wales and her three children is likely."
