Prince Harry's tell-all memoir Spare has "done Princess Kate a favour", according to a royal expert.
A year on since the book's release, the Duke of Sussex broke the all-time sales record for a non-fiction book, with over three million copies sold worldwide.
In the book, the Prince made several scathing claims about the Royal Family, including his brother Prince William and father King Charles.
Harry also accused the Prince of Wales of a physical attack in his former home shared with Meghan Markle, Frogmore Cottage.

The book also revealed the fallout from Meghan and Harry's decision to step down as senior working royals in 2020, after Meghan's battle with poor mental health.
Prince Harry documented wife Meghan's "crying on the floor" on various occasions, as they navigated their new life in California.
Speaking to GB News, Royal Editor for the Mail on Sunday, Charlotte Griffiths, claims the passages written about the Duchess crying has "done Kate a favour".
She adds that it shows a "strength" of the Princess of Wales, after many reports of the pair falling out over issues such as Meghan's wedding to Harry.
Griffiths told GB News: "Spare did her a favour, because Harry wrote every other chapter about how Meghan was on the floor crying.
"There's always been this narrative from Meghan and Harry's camp that Meghan is the strong one and Kate is the weak one.
"But Spare portrayed Meghan as this weak, flailing character on the floor, and actually Kate is the tough one that made Meghan cry. We are getting this picture emerging of Kate as a bit of a tough cookie underneath it all."
She added: "She's [Kate] had a brilliant year and she's had the Coronation as well, where she just looked fabulous. She's running a tight ship with her family and she's getting tougher and tougher as the years go by."

When questioned by host Mark Dolan if there's any hopes of a reconciliation between the Princess of Wales and Duchess of Sussex, Griffiths admitted it "isn't likely", but Kate would use her strength to "put on a good show" if the time came.
Griffiths revealed: "They were never friends in the first place. I think Kate could probably put on a good show if she had to.
"A bit like when the Queen died, they had to walk around the crowds together. That wasn't too convincing, but she might be able to do a more convincing double act if it came to it many years down the line, and they ended up doing a royal engagement together again."
She continued: "I think Catherine was quite cool towards Meghan and never particularly warm to her. But Meghan didn't give her any leeway for that. Meghan expected a hug on their first meeting, and turned up with no shoes on."
