Prince Harry said he received a 'horrible reaction' from the royal family on the day of Queen Elizabeth's death

• Prince Harry said he had a "horrible reaction" from the royals when the Queen died.
• Harry opened up about the experience in his ITV interview with Tom Bradby on Sunday.

The Duke of Sussex spoke in his new ITV interview with Tom Bradby about the "horrible reaction" he received from the royal family after Queen Elizabeth II died.

Prince Harry spoke with Bradby to promote his memoir, "Spare," which will be published worldwide on Tuesday. In the interview, which aired in the UK on Sunday, Harry said the last time he saw his family was during the Queen's funeral in London on September 19.

Queen Elizabeth died at her Balmoral Castle estate on September 8. She was 96.

Harry said that while he initially thought the funeral would be a "good opportunity to bring family together," the reality was different.

"But the day that she died was just a really, really horrible reaction from my family members... then the briefings, then the leaking, then the planting. I was like, 'We're here to celebrate the life of granny, and to mourn her loss. Can we come together as a family?'" he said.

"I don't know how we collectively change that," he added.

Buckingham Palace did not immediately respond to Insider's request for comment.

Two days after the Queen's death, Harry, his wife Meghan Markle, his brother Prince William, and his sister-in-law Kate Middleton were photographed on a walk to view tributes to the late monarch at Windsor Castle. Sources told People that security didn't expect all four royals to appear together at the property, adding that William thought the walk would be an important show of unity.

Entertainment Tonight also reported that William reached out to Harry an hour before their promenade and asked if he and Meghan would like to join.

The prince also spoke about Buckingham Palace and the press in his docuseries

The couple also talked about the royal family's relationship with the press in their docuseries "Harry & Meghan," which premiered on Netflix in December. In one episode, Harry recalled an email exchange with his father, King Charles III, in early 2020, in which he discussed a potential move to Canada.

In the exchange, the prince said he also mentioned that he and Markle were willing to give up their royal titles to make the move. Harry said his proposition was reported in the press less than a week later, which he said was a common occurrence in the months leading up to his family's exit from royal life.

Harry said in a clip from his upcoming interview with Anderson Cooper, set to air Sunday on "60 Minutes," that he believed Buckingham Palace had previously planted stories about him and Meghan.

"They will feed or have a conversation with the correspondent, and that correspondent will literally be spoon-fed information and write the story. And at the bottom of it, they will say that they've reached out to Buckingham Palace for comment, but the whole story is Buckingham Palace commenting," Harry told Cooper in the "60 Minutes" clip.
