It’s understood the Queen approved the move, which means Prince Charles, Prince William et Prince Andrew will wear costumes at the ceremony on Saturday.

Protocol suggests that he can only wear a costume with medals.
Andrew and Charles had to wear the uniform thanks to their service in the Royal Navy – Andrew would have considered the admiral’s uniform.
He was scheduled to be promoted to rank last year, but was “postponed” when he stepped down due to outcry over his links with Jeffrey Epstein.
Prince William served in both the Army and the RAF.
The uniform turn-around was “the most telling solution to the problem,” a military source told The Sun.
Ahead of the funeral, the Queen held a ceremony at Windsor Castle on Wednesday to officially welcome her new Lord Chamberlain, former MI5 boss Baron Parker.
He will globally control the funeral in his new post as the highest official in the royal household.
Saturday’s funeral is taking place in St George’s Chapel in Windsor and will have just 30 guests due to coronavirus restrictions.
Under the plans, the Duke’s coffin will be transported to the chapel on a specially modified Land Rover, which he helped design.
The Prince of Wales and other members of the Royal Family will participate in the procession on foot.
With the royal family still mourning the death of the Duke, a unpublished photo of Philip and the Queen with seven of their great-grandchildren was also released yesterday.
