The Duke of York appeared visibly overcome with emotion as he escorted his mother's coffin to her funeral at Westminster Abbey on Monday.
Prince Andrew joined his brother King Charles and other senior royals – including the Princess Royal, the Prince of Wales and the Earl of Wessex – in walking behind the Queen as the country came together in a final farewell.
The late monarch's coffin was brought from Westminster Hall, where it had been lying in state, to sit on top of a gun carriage as it was transported to the Westminster Abbey ceremony on Monday morning.
As the drummers and bagpipes began to play and the procession pulled out of Westminster Hall, Andrew appeared to hold back tears, before steeling himself alongside his family.

Andrew paid tribute to his mother the Queen on Sunday evening, as the nation held a minute’s silence to mourn the late monarch’s death.
Andrew is the latest royal to pay tribute to his mother, hailing her “knowledge and wisdom infinite, with no boundary or containment”, adding: “I will miss your insights, advice and humour”.
He described the Queen as “Mummy, Mother, Your Majesty, three in one” and said it had been an “honour and privilege” to serve her.
The state funeral was held for the Queen on Monday, as her coffin was pulled from Westminster Hall to Westminster Abbey by service members of the Royal Navy.
Andrew, the late monarch’s second son, stepped down from public life after the furore over his friendship with paedophile billionaire Jeffrey Epstein, and paid millions to settle a civil sexual assault case to a woman he claimed never to have met.
In January, ahead of his legal settlement, his mother the Queen stripped him of all of his honorary military roles, including Colonel of the Grenadier Guards, and he gave up his HRH style.
Andrew, a former Royal Navy officer who served in the Falklands War, retained his rank as a Vice Admiral.
While working royals including the King, the Prince of Wales, the Princess Royal and the Earl of Wessex have paraded in military uniform at the state funeral and on other occasions in the next week, Andrew was not permitted, apart from a vigil he attended with this siblings.
