With the publication of his candid memoir "Spare," Prince Harry captured the public's attention. The book revealed Prince Harry's long-running animosity toward his brother, Prince William.

Accusations of physical altercations and minor disagreements between Prince Harry and his siblings are detailed in the book. It appears that their problems have deep roots that date back to their early years.

In one passage, Prince Harry complained that Prince William, as the heir, was given preferential treatment in their shared bedroom at Balmoral. One of Balmoral's fifty bedrooms, he said, had been partitioned off for him and "Willy," with the adults calling it the nursery.

"Willy had the larger half, with a double bed, a good-sized basin, a cupboard with mirrored doors, a beautiful window looking down on the courtyard, the fountain, the bronze statue of a roe deer buck," Prince Harry wrote.

"My half of the room was far smaller, less luxurious. I never asked why. I didn't care. But I also didn't need to ask. Two years older than me, Willy was the Heir, whereas I was the Spare,” the husband of Meghan Markle claimed.

According to Prince Harry, Prince William instructed him to act as if they were strangers when he first arrived at Eton, as stated elsewhere in the book, The Mirror reported.

"For the last two years, he explained, Eton had been his sanctuary. No kid brother tagging along, pestering him with questions, pushing up on his social circle. He was forging his own life, and he wasn't willing to give it up,” Prince Harry penned.

Considering Prince William supposedly "loathed it" whenever Princess Diana wore them matching clothing or when "anyone made the mistake of thinking us a package deal," Prince Harry was not surprised by his sentiment.

Concerns over Prince Harry's future in the royal family have grown as a result of the deterioration of his relationship with Prince William.

The Duke and Duchess of Sussex reportedly wanted nothing more than to spend Christmas in the UK with The Firm, but they ended up spending the holiday season in Montecito, California, instead. As they assembled in Sandringham, the members of the royal family maintained an air of unity.

The Sussexes, according to royal expert Phil Dampier, blew a golden chance to mend fences with the royal family. According to him, Meghan and Prince Harry would have been more popular if they had spent Christmas together, Express UK reported.

"Harry and Meghan have let it be known that they see 2024 as their year of redemption, to which my reaction is good luck with that. It's a trite phrase dreamt up by their Hollywood PR people and in reality means very little. Actions speak louder than words," Phil stated.
