Princes Harry and Andrew, who no longer perform senior royal duties, will not wear uniforms in which they have previously been seen at a string of events. Her Majesty passed away last Thursday at the age of 96 in what is understood to have been one of her favourite residences.
Elizabeth II’s state funeral will take place on September 19.
This day will also be a bank holiday, King Charles III has revealed.
At this and four other events next week, working royals will parade in military uniform.
These include the King, the new Prince of Wales (Prince William, formerly the Duke of Cambridge), the Princess Royal and the Earl of Wessex.
“The Duke of York will continue not to undertake any public duties and is defending this case as a private citizen.”
The Duke of York has retained his rank as Vice Admiral, having served in the Falklands War in the Royal Navy.
Despite this, he will only wear uniform at one event marking the death of his mother, according to reports.
This will be at the vigil in Westminster Hall and is considered a “special mark of respect” for Her Majesty.
Other formal events marking Her Majesty’s passing are the service of thanksgiving at St Giles’ Cathedral in Edinburgh, the procession to – and following service of prayer at – Westminster Hall and a committal service at St George’s Chapel, Windsor.
New York Times writer Omid Scobie has reported in a post on Twitter that “unlike Prince Andrew, Prince Harry will not be allowed to wear uniform at the final vigil in Westminster Hall”.
He said this would be a “huge blow for the Duke of Sussex, who served for 10 years and this morning spoke of the Queen being his ‘commander-in-chief’”.
Prince Andrew is expected to wear a morning suit to his mother’s funeral, as he did for that of his father, Prince Philip.
