Prince Harry and Prince Andrew were not allowed to perform a salute during the Queen's coffin procession - despite several of the other royals giving the symbolic gesture.
As the parade travelled from Buckingham Palace to Westminster Hall, it travelled along Whitehall - where the Cenotaph is located. While other royals in uniform saluted the national memorial to the war dead - all Andrew and Harry could do was bow their heads as they were not wearing military uniform. It was the same as they arrived at Westminster. Most of the senior members of the Royal Family wore military uniform today as the Queen makes her final journey after her sad death last Thursday.
The new monarch King Charles, Princess Anne, Prince Edward and Prince William are all in military uniform for the special occasion - but despite both seeing active service, Harry and Andrew are in morning suits as they are no-longer working royals .
However, sources have said Prince Andrew will be allowed to do so as a "special mark of respect" for the Queen at the final vigil in Westminster Hall when he stands guard around her coffin.
The Duke of York, who retained his rank as a Vice Admiral, is expected to wear the corresponding uniform. Andrew stepped down from public life after the furore over his friendship with paedophile billionaire Jeffrey Epstein.

His nephew, Prince Harry, is not wearing military uniform today and won't for any of the upcoming occasions.
Harry, who saw action on the front line during two tours of duty in Afghanistan, will be in civilian dress for official events including the funeral.
On Tuesday, the Sussex spokesperson said: "[Prince Harry] will wear a morning suit throughout events honouring his grandmother.
"His decade of military service is not determined by the uniform he wears and we respectfully ask that focus remain on the life and legacy of Her Majesty Queen Elizabeth II." .
It comes as the Queen's coffin left Buckingham Palace for the final time and went to Westminster Hall, where a 20-minute service is being led by the Archbishop of Canterbury accompanied by the Dean of Westminster.
Escorting the coffin on foot from the Palace were the King and his three siblings, Prince Andrew, Princess Anne and Prince Edward and the Queen's grandsons Peter Phillips, Prince William and Prince Harry, who stood shoulder to shoulder.
Also taking part were Anne's husband Vice Admiral Sir Tim Laurence, the Earl of Snowden - Princess Margaret's son - and the Duke of Gloucester - a cousin of the Queen.
Now up to 400,000 people are expected to brave a 12-hour wait on the banks of the Thames to catch a glimpse of the Queen's coffin as she lies in state for four days ahead of her funeral on Monday.
Today's procession to Westminster comes after there were emotional scenes last night when the Queen's coffin was brought back to London from Edinburgh.
The Queen's grandchildren, including Harry and William - the new Prince of Wales - and their wives Meghan and Kate, were among members of the royal family paying their respects to the late monarch by witnessing her coffin’s arrival at Buckingham Palace.
