Queen's grandson Prince Harry and his wife Duchess Meghan want to take part in the celebrations for Queen Elizabeth II's 70th throne anniversary together with their two children.
It will be the first time the Queen has met her 11-month-old great-granddaughter Lilibet, who is named after the monarch's family nickname.
The couple was thrilled and honored, a spokeswoman said on Friday.
However, the family will not be seen alongside the Queen on the balcony of Buckingham Palace to kick off the anniversary weekend on June 2nd.
The second oldest Queen's son Prince Andrew will also be missing there, as reported by the BBC and Sky News, citing palace sources.
The Queen will only be accompanied by members of the Royal Family "who are currently taking on official public duties on behalf of the Queen," it said.
The 62-year-old Andrew had largely withdrawn from public life years ago because of allegations of sexual abuse of a minor.
He had recently averted a lawsuit in the USA, allegedly by paying millions in damages.
Shortly thereafter, the Queen was led by her second eldest son to a service at Westminster Abbey.
The gesture had caused criticism.
Prince Harry (37), son of heir to the throne Prince Charles, and his wife Duchess Meghan (40) moved to the United States about two years ago and gave up their royal duties.
They then made serious allegations against the palace.
Since then, relations have been strained.
The Queen has determined that only "working royals" and their children are allowed to appear on the balcony, the reports said.
This also excludes Harry and Meghan and their children Archie (3) and Lilibet.
At the side of the 96-year-old Queen, her other children – Prince Charles, Princess Anne and Prince Edward – as well as Harry's big brother Prince William and their families are expected.
Several events are planned in London from June 2-5, including a military parade, a memorial service and a major concert.
The Queen, who recently canceled several events due to health problems, wants to be personally present at some program points.
However, there should only be a confirmation shortly beforehand, as the BBC reported.
