It's been suggested that the Duke may seek comfort in the company of his cousin, Princess Eugenie, as some other members of the royal family are expected to avoid him at the event.
Harry has a strong relationship with Eugenie and is expected to appreciate spending time with her during the celebrations.
Junior members of the royal family are anticipated to engage with him during the event, and it will be the first time he sees his family since the publication of his memoir and the release of his Netflix docu-series with Meghan.
Although the Duke has faced criticism from some quarters, he is said to consider it his duty to attend the Coronation, as it's an important moment in his life.
Kinsey Schofield, a royal expert, revealed that it was Prince Charles' wish that Harry attend and he expects Harry to have small talk with his cousins Zara Tindall and Princess Eugenie at the event.
