The trio was expected to join Her Majesty for the traditional Trooping the Colour RAF flypast, however, "after careful consideration" they will now be excluded.
A Palace spokesperson said: "After careful consideration, the Queen has decided this year's traditional Trooping the Colour balcony appearance on Thursday 2nd June will be limited to Her Majesty and those members of the royal family who are currently undertaking official public duties on behalf of the Queen."
The announcement has been interpreted by many as a snub to the Duke and Duchess of Sussex and Andrew.
Harry and Meghan stepped down as senior members of the royal family in 2020, while Andrew recently settled his US civil sex assault case and was stripped of his York title.
There were doubts about whether Harry, Meghan and their two children would fly in for the celebrations, however, the couple confirmed minutes after the Queen's statement that they will be there with Archie, three, and Lilibet, 10 months.
Just 18 minutes after the Palace's statement, Harry and Meghan revealed via their friend and journalist Omid Scobie, who Tweeted, "From a Sussex spokesperson: 'Prince Harry and Meghan, The Duke and Duchess of Sussex are excited and honoured to attend The Queen’s Platinum Jubilee celebrations this June with their children.'"
According to the Daily Mail, the couple may still make a starring appearance at the pageant finale with senior royals and possibly even appear as part of a second balcony appearance.
The publication reports that the decision to include the pair will likely make other members of the royal family uncomfortable, particularly Prince William who has "been left deeply hurt and angered by Harry's behaviour".
Sources suggest, however, that the brothers will no doubt put their feelings to one side for their grandmother.
"Despite what has happened in recent years and what may be yet to come given that Harry's memoirs have yet to come out, family members will accept the Queen's olive branch in the spirit it was extended. The body language will be fascinating, mind you," one insider said.
The 17 other family members who will appear alongside Her Majesty on the balcony will be: Charles and Camilla; William and Kate with George, Charlotte and Louis; Edward and Sophie and their children Louise and James; Princess Anne and Vice Admiral Sir Tim Laurence; the Duke and Duchess of Gloucester; the Duke of Kent and Princess Alexandra.
Prince Andrew's daughters Beatrice and Eugenie will not appear on the balcony, however, it's believed the Queen is still making an effort to include them.
