Prince Harry made headlines on Wednesday after Buckingham Palace revealed he will be attending King Charles' coronation without his wife Meghan Markle - but will he have a role in the proceedings?
HELLO!'s royal editor, Emily Nash, explained: "I'd be surprised if he had a specific role, I think he will attend the ceremony like other members of the royal family without necessarily taking part.
"But I think that just his presence is a big moment after all the difficulties his family has been through particularly since the publication of Spare. It says a lot that he's coming and that he's prepared to be there on the day. "
Traditionally, blood princes do play a role in coronation proceedings which would include paying homage to the monarch by placing their hands between the King's and swearing allegiance, touching the crown and kissing the King's left cheek.
There have been suggestions that only William will carry out the ritual in May, but Buckingham Palace is yet to reveal the official plans for the day.
Other traditions royal family members are expected to take part in during the historic day include the royal procession and an appearance on the balcony of Buckingham Palace.

Charles and Camilla will travel back from Westminster Abbey in a horse-drawn Gold State Coach, taking a slow 1.3-mile route to the Palace as part of a military parade.
During his last appearance in the UK at the Queen's funeral, Harry and Meghan sat in the second row behind The King and Queen Consort. It hasn't been confirmed where Harry will be sitting but it will most likely be amongst other royal family members. However, seating arrangements usually have a different format at coronations to weddings and funerals.
Harry is expected to make a swift return to California to reunite with his family as soon as the official proceedings conclude.
