Prince Harry 'Upset' He Was 'Ignored' At Jubilee, 'Feels He's Owed Apology,' Biographer Claims

Prince Harry and Meghan Markle kept a low profile during the Platinum Jubilee celebrations, but a biographer of the duke suggested that he may have been upset because they were "largely ignored" by his family members.

The Duke and Duchess of Sussex returned to the U.K. last week with their kids Archie, 3, and Lilibet, 1, for the Queen's Platinum Jubilee. However, the couple was notably absent from most events during the four-day festivities.

Angela Levin, author of "Harry: The Biography of a Prince," weighed in on Prince Harry and Markle's recent U.K. trip, suggesting that Prince William's younger brother likely wasn't happy with the way he was treated during the Jubilee.

"I think he would have been very, very upset that he was largely ignored," the royal expert told The Sun of Prince Harry. "He still feels he's owed an apology."

However, Levin, who spent a year with the Duke of Sussex while writing his 2018 biography, felt that it was Prince Harry who needs to apologize to his family for the comments he's made about them since stepping back from his role as a senior working royal and moving to California with his wife in 2020.

"But he's the one who should apologize. He said during the Oprah interview that Charles and William were trapped, he said he'd been cut off by his father," she continued. "You can't just go around being rude about people and expecting them to open their hearts to you again."

While they were not seen publicly interacting during the Jubilee celebrations, it was reported that Prince Harry and Markle extended an olive branch to Prince William and Kate Middleton, inviting them to their daughter Lilibet's first birthday party Saturday.

However, the Duke and Duchess of Cambridge reportedly declined their invitation. Prince William and Middleton visited Cardiff Castle in Wales that day with their two eldest children, Prince George and Princess Charlotte, and attended the "Platinum Party at the Palace" concert at Buckingham Palace later that evening.

"Allegedly, they asked Kate and William and the children to the party," Levin said. "However, they didn't take the trouble of finding out the Cambridges would be in Wales on the morning and coming back to get ready for the Jubilee concert in the afternoon, so they couldn't go."

Prince Harry and Markle attended just two Jubilee events. They watched Trooping the Colour, the Queen's annual birthday parade, from the Major General's Office on June 2 and attended the Service of Thanksgiving in honor of the monarch at St. Paul's Cathedral, where they were greeted with a mix of cheers and boos.

The Duke and Duchess of Sussex quietly left the U.K. and flew back home to California Sunday, skipping the Platinum Jubilee finale.

Royal correspondent Omid Scobie told "BBC Breakfast" on June 3 that Markle and Prince Harry had always planned to keep a "low profile" during their visit to the U.K.

"I spoke with people close to the couple... who said that they want to be as low-profile as possible during this trip," the "Finding Freedom" author was quoted as saying by the Independent. "It's almost hard to believe, but I think yesterday Trooping the Colour was a great example. We didn't really catch sight of them on TV cameras."
