KEY POINTS

  • The palace released the order of service for Queen Elizabeth II's state funeral Monday
  • Prince George and Princess Charlotte will walk behind the late monarch's coffin for the procession in Westminster Abbey
  • They will follow right after their parents, Prince William and Kate Middleton, and in front of Prince Harry and Meghan Markle.

Prince William and Kate Middleton's two eldest children, Prince George and Princess Charlotte, will attend Queen Elizabeth II's funeral Monday.

Prince George, 9, and Princess Charlotte, 7, will walk behind their great-grandmother's coffin for the procession in Westminster Abbey Monday, Us Weekly reported, citing the order of service for Queen Elizabeth's state funeral released by the palace Sunday. The siblings will be in front of their uncle Prince Harry and aunt Meghan Markle.

According to the program, all attendees will stand as the procession of the coffin enters Westminster Abbey, and the Queen's coffin will be followed by her descendants.

King Charles III and Queen Consort Camilla will be first in the procession, to be followed by Princess Anne and her husband Sir Tim Laurence. Prince Andrew will then walk solo ahead of Prince Edward and his wife, Sophie, Countess of Wessex.

Behind the late monarch's children and their spouses will be her grandchildren and their spouses. Prince William and Middleton will walk behind Prince Edward and Countess Sophie.

The Prince and Princess of Wales will be followed by Prince George and Princess Charlotte. Their youngest child, Prince Louis, 4, was not on the list for the procession. Prince Harry and Markle will follow the two children.

Next on the list are the Princess Royal's son Peter Phillips and David Armstrong-Jones, the Earl of Snowdon and the son of Queen Elizabeth's sister, Princess Margaret.

Rounding out the family segment of the procession will be the Queen's first cousins: Prince Richard, Duke of Gloucester, Prince Michael of Kent and Prince Edward, Duke of Kent.

Prince George and Princess Charlotte are not included in the order of service for the committal service for later in the day, which will take place at St. George's Chapel in Windsor Castle, according to People.

Prince Harry reunited with his older brother Prince William after their grandmother died at age 96 on Sept. 8.

King Charles' two sons made a public appearance together on Sept. 10, when they greeted mourners and viewed floral tributes for the Queen outside Windsor Castle alongside their respective wives.

Prince William reportedly invited his younger brother on the walkabout to show solidarity, but it "wasn't an easy decision" for him to make, an unnamed source told Us Weekly.

"In the end, [William] elected to [invite them] because it was agreed amongst all of them that this very much the appropriate thing to do," the insider added.

An unnamed source close to Prince Harry told the Sunday Times of London that the Duke of Sussex has found it "difficult" to be in his brother's company at times over the past week.

But although the brothers are "uncomfortable" around each other, they are "trying their best" to get along, the insider claimed.
