• Princes Harry and William will not be standing next to each other when they reunite at Philip's funeral Saturday
  • Only close family members will attend the Duke of Edinburgh's funeral at St. George's Chapel
  • None of the royals will wear a military uniform to the service, a report says

Prince Harry and Prince William will not walk side-by-side during their grandfather Prince Philip's funeral on Saturday.

On Thursday, Buckingham Palace released the broad outlines of the funeral program for the late Duke of Edinburgh, who died April 9 at 99, ABC News reported. According to the statement, Prince Harry will not be walking next to his older brother as they escort their grandfather’s coffin into St. George’s Chapel at Windsor Castle, west of London.

Their cousin and the son of Princess Anne, Peter Phillips, will walk between the allegedly feuding Duke of Sussex and Duke of Cambridge.

For the second procession into the chapel, Prince William will walk with Phillips with Prince Harry behind them. Next to Prince Harry will be David Armstrong-Jones, the son of Princess Margaret and Antony Armstrong-Jones, E! News added.

Prince Charles and his sister, Princess Anne, will lead the 15-member procession.

Palace officials refused to comment when asked whether Prince William and Prince Harry's arrangement had something to do with the reported tension between the Duke of Sussex and the royal family, per ABC News.

"We’re not going to be drawn into those perceptions of drama or anything like that," a palace spokesman told the outlet while speaking on condition of anonymity in line with policy. "This is a funeral and the arrangements have been agreed and they represent Her Majesty’s wishes."

Princess Diana and Prince Charles' sons haven't seen each other in person since the Duke Sussex stepped away from royal duties and moved to California with his wife Meghan Markle and their son Archie last year. This will also be the first time they are coming face-to-face since Prince Harry and Markle's interview with Oprah Winfrey in March.

Markle, who is heavily pregnant with their second child, was not able to join her husband after her doctors advised her against traveling.

"Meghan will be staying in California. She can’t go on doctor’s orders," an unnamed source told Us Weekly. "She is too far along to fly and it’s recommended she rest in the final months."

"They’re taking this precaution seriously because she miscarried before. Doctors don’t think the stress of it all is worth her risking losing another baby," the insider continued.

Meanwhile, the private ceremony for the Duke of Edinburgh will have a maximum of 30 guests, who will mostly be close family members, plus three of Prince Philip's relatives from Germany.

Aside from his wife of 73 years Queen Elizabeth II, other attendees include Camilla Parker Bowles, Kate Middleton, Prince Andrew, Prince Edward, Princess Beatrice and Princess Eugenie and their respective husbands.

The royal family will not be wearing military uniforms to the ceremony, multiple outlets, including ITV, earlier reported. ITV indicated that it was the Queen who made the decision to require mourning dress instead of military uniforms and suggested that it was to spare the family "embarrassment" for Prince Andrew and Prince Harry, who are no longer entitled to wear their uniforms.
