The Duke of Sussex is not given the chance to wear military uniform as he mourns the Queen, although his disgraced uncle, the Duke of York, will be allowed to do so at the state vigil.
Harry, who saw action on the front line during two tours in Afghanistan, will be in plain clothes for official events, including the late monarch’s state funeral.
Only members of the royal family – who are not Harry and Andrew – are allowed to dress in uniform at five ceremonies.
These include the service at St Giles Cathedral in Edinburgh on Monday, and the procession through Westminster Hall, the vigil in state, the funeral at Westminster Abbey and the ceremony at Windsor.
But an exception has been made for Andrew, who will wear an outfit as a “special mark of respect” for the Queen when he stands guard around her coffin during the Princes’ Vigil.
He is expected to be joined by the Queen’s other children – the King, Princess Royal and the Earl of Wessex – in the process during the state fast later this week.
It is likely to be a bitter blow for ex-soldier Harry, who is proud of his decade in the forces, and who was saddened to be stripped of his honorary military roles, including Captain of the Royal Marines by the Queen after Megxit .
Earlier on Monday, he wrote about his special memories of the time the Queen watched him pass out in 2006 when he became an officer in the British Army.
He spoke of his “first meeting” with his grandmother as “My Chief” – and is believed to have been referring to the occasion when the late monarch made him smile and blush while she was telling the cadets.
A source confirmed that Harry – whose rank is captain – would not be in uniform for any event.
Andrew resigned from public life after the furore over his friendship with pedophile billionaire Jeffrey Epstein.
He went on to pay millions to settle a civil sexual assault case against a woman he claimed he had never met.
In January, before his legal settlement, the Queen stripped him of all his honorary military roles, including Colonel of the Grenadier Guards, and he dropped the style of HRH.
Andrew, a former Royal Navy officer who served in the Falklands War, has retained the rank of Vice-Admiral and is expected to wear the matching uniform.
Virginia Giuffre sued him for allegedly sexually assaulting her when she was 17 after being trafficked by Epstein. Andrew denied the allegations.
At the service of thanksgiving at St Giles on Monday, Andrew wore a morning suit while his brothers, including Edward who retired from the Royal Marines, wore military dress as they processed behind the Queen’s coffin.
Andrew wore eight medals and decorations – the South Atlantic Medal for Service in the Falklands, his Silver, Gold, Diamond and Platinum Medals, Royal Navy Long Service Medals with Bars, Canadian Forces Decoration with Bars and New Zealand Memorial Medal.
At the Duke of Edinburgh’s funeral in April 2021, the issue of dress was addressed by the Queen, who ruled that no member of the Royal Family should wear a uniform.
It was a break with tradition, but it was seen as the most eloquent solution to the problem.
Reports had suggested that Andrew was considering donning an admiral’s uniform.
He was due to be promoted to Rear Admiral in 2020 to celebrate his 60th birthday, but this did not go ahead after the fallout from his disastrous appearance on Newsnight.
