Watch: Prince Philip funeral: Queen leads royals at ceremony in Windsor as she bids farewell to Duke of Edinburgh
The Queen mourned alone inside St George's Chapel at the Windsor Castle funeral of her "strength and stay" Prince Philip.
The 94-year-old monarch accompanied the Duke of Edinburgh’s coffin to its final resting place in the funeral on Saturday afternoon.
In line with coronavirus rules, there were just 30 mourners at the service in the chapel who all wore masks and were socially distanced.
The service reflected his deep association with the Royal Navy and was planned with a high level of involvement from the duke himself, including readings and hymns requested by him.
The Queen's second son Prince Andrew sat two seats away from her, while Princess Anne and her husband Vice Admiral Sir Timothy Laurence were two seats down from Andrew.
A simple service was led by the Dean of Windsor, David Connor, with a reading and blessing from the Archbishop of Canterbury, Justin Welby.
The Queen joined the procession of her husband's coffin through the grounds of Windsor Castle in a state Bentley, accompanied by her lady-in-waiting, Susan Hussey.
However the limited numbers allowed at funerals meant Hussey was not able to accompany Her Majesty into the quire and had to remain in the nave of St George's Chapel, were the service was held.
Watch: Britain falls silent in tribute to Prince Philip
In following the procession, which included all of the duke and the Queen's children and three of their grandsons, she followed him for the first time.
As monarch, he had always had to remain two steps behind her at formal engagements.
The Queen's family had to keep socially distant through the funeral, with mourners allowed to sit only in their households.
The quire is usually a place of celebration for the Royal Family.
St George's Chapel is where the Queen and duke's grandchildren Prince Harry and Princess Eugenie married their spouses Meghan Markle and Jack Brooksbank in 2018.
The Queen had not been seen in public since the death of her husband on 9 April, at the age of 99.
Her children and grandchildren have at various stages through the last week been paying tribute to the Duke of Edinburgh and viewing flowers and cards left by members of the public.
Despite being in mourning, the Queen did carry out two engagements, listed in the Court Circular, including a retirement meeting for her former Lord Chamberlain.
She will remain in royal mourning until 22 April, the day after her 95th birthday.
