In one excerpt, the Duke of Sussex revealed the gift his mother had left him after her passing. The Duke of Sussex explained that he wasn't exactly sure when the event took place, but described the vivid memory of being with his dad, King Charles and his aunt, Sarah Ferguson.

He wrote that Sarah stepped forward with two tiny blue boxes. "What's this? ," he asked before being told to open it. The heartbreaking gift, Harry was told, was a lock of his mother's hair. Harry continued: "Aunt Sarah explained that, while in Paris, she'd clipped two locks from Mummy's head."

Elsewhere in his book, Harry admitted he misses his mother every day, but played down people's comparisons of her to the likes of Mother Teresa. He instead explained how his mother was "simply indescribable".

Describing his feelings years after the loss of his mother, Harry opened up: "How was it possible that I could see her, clear as the swan skimming towards me on that indigo lake? How could I hear her laughter, loud as the songbirds in the bare trees-still? There was so much I didn't remember, because I was so young when she died, but the greater miracle was all that I did."

This weekend, Prince Harry is believed to have been grappling with "regrets" for missing out on Trooping the Colour . The event, also known as the King's Birthday Parade, went off without a hitch, yet Harry and his wife Meghan Markle were conspicuously absent.

Royal expert Richard Fitzwilliams weighed in, suggesting that the Duke of Sussex might be feeling remorseful about not attending. Speaking to The Sun , he said: "I think when it comes to military matters Harry has always taken an interest. I think that he does unquestionably view the way the break has occurred with the Royal Family. Which, as I say in my opinion, is the fault of the Sussexes."
