Royals Prince Harry and Prince William Were Set to Work 'Side-by-Side': Harry 'Was the Secret Weapon' Prince Harry has been compared to his older brother his entire life — and it's "not terribly good for your self-confidence," says a source By Stephanie Petit Stephanie Petit Stephanie Petit is a Royals Writer and Reporter at PEOPLE. People Editorial Guidelines and Simon Perry Published on January 16, 2020 11:55 AM Share Tweet Pin Email While Prince William is the future king, Prince Harry was expected to play an important — even if supporting — role in the future of the monarchy. “Courtiers imagined in the future that Harry would be shoulder-to-shoulder with William when he was King,” Penny Junor, author of Prince Harry: Brother, Soldier, Son, tells PEOPLE in this week’s cover story. “He would pick up the bits that William wouldn’t be as good for. They would be complimentary and side-by-side throughout their lives.” “That was a lovely picture,” she continued. “Harry was the secret weapon, really.” However, a schism between the brothers deepened over the past years. Multiple sources previously told PEOPLE that tensions rose back when Harry first told his family he wanted to marry Meghan Markle after less than a year of dating. An insider says William, who dated college sweetheart Kate Middleton for about eight years before tying the knot, cautioned Harry that things were moving too quickly, leaving the younger sibling angry and hurt.

However, Prince Harry dealt with being known as “the spare” to his older sibling from his birth. “It’s not terribly good for your self-confidence,” says Junor. “He was always compared to William: William was the good-looking one, the important one, the clever one. Harry was the also-ran. I think that did take a toll on him.” Prince Harry ‘Cut Off’ Close Friends During Meghan Markle’s Pregnancy: ‘There’s a Lot of Resentment’ Prince Harry, Meghan Markle and Archie.

And when Archie was born, the couple’s focus shifted even more to “doing what’s right for their family,” adds another friend. On Monday, the brothers traveled to Sandringham for a family summit with grandmother Queen Elizabeth and father Prince Charles to discuss Harry and Meghan’s decision to step down as senior royals. After a 90-minute discussion, the Queen released the following statement: “Today my family had very constructive discussions on the future of my grandson and his family,” the Queen said in a statement. “My family and I are entirely supportive of Harry and Meghan’s desire to create a new life as a young family. Although we would have preferred them to remain full-time working Members of the Royal Family, we respect and understand their wish to live a more independent life as a family while remaining a valued part of my family. “Harry and Meghan have made clear that they do not want to be reliant on public funds in their new lives. It has therefore been agreed that there will be a period of transition in which the Sussexes will spend time in Canada and the UK. These are complex matters for my family to resolve, and there is some more work to be done, but I have asked for final decisions to be reached in the coming days.” Can’t get enough of PEOPLE‘s Royals coverage?
