We now hear from a series of military bands, beginning with the Pipe Major of The Royal Regiment of Scotland who plays a lament.

The Last Post, the famous bugle call played at military funerals and memorials, is sounded by the Buglers of the Royal Marines.

The final note of the bugle call hangs in the air for a moment and resonates around the chapel before the State Trumpeters of the Household Cavalry sound the Reveille.

That's followed by the Buglers of the Royal Marines sounding Action Stations - a signal that all hands should be ready for battle, and an apt tribute for the duke, who "would want us to get on with the job" as Prince William noted.

The Duke of Edinburgh has been interred in the Royal Vault of St George’s Chapel.

Before the coffin was lowered into the vault, the dean said: "Go forth upon thy journey from this world, O Christian soul."

His coffin was placed on a catafalque on a marble slab in the Quire and lowered into the vault by electric motor.

The Duke of Edinburgh's coffin is draped in his 12ft personal standard and decorated with a wreath of flowers chosen by the Queen, as well as his Admiral of the Fleet Naval Cap and sword.

The Earl and Countess of Wessex, and their children, and the Duke and Duchess of Cambridge are seen in the image above.

Now the Garter Principal King of Arms, who is the principal adviser to the sovereign on matters of ceremony and heraldry, reads out the Duke of Edinburgh's titles in full.

"Thus it hath pleased Almighty God to take out of this transitory life unto his divine mercy the late most Illustrious and most Exalted Prince Philip, Duke of Edinburgh," he begins.

The long list runs from Earl of Merioneth and Baron Greenwich to Admiral of the Fleet, Field Marshal in the Army and Marshal of the Royal Air Force.

He ends the list with the duke's most famous role, husband to the Queen, "whom may God preserve and bless with long life, health and honour and all worldly happiness".

The choir sings the funeral anthem, the Russian Kontakion of the Departed.

"Give rest, O Christ, to thy servant with thy Saints," they sing. "Where sorrow and pain are no more."

It ends on a note of praise: "Alleluia, Alleluia, Alleluia".

The Queen is seated at the front of the quire, nearest the altar. Directly opposite her is the Prince of Wales alongside the Duchess of Cornwall.

Closest to the Queen, two seats to her left, is the Duke of York.

In the archbishop's next prayer, he offers words of comfort for the mourners, 30 of them gathered in St George's Chapel and many more watching around the world.

"Almighty God, Father of all mercies and giver of all comfort," he says. "Deal graciously, we pray thee, with those who mourn; that casting every care on thee they may know the consolation of thy love."

"God save our gracious Sovereign and all the Companions, living and departed, of the Most Honourable and Noble Order of The Garter," says the Dean of Windsor as the congregation respond: "Amen."

He offers praise to God for the life of Prince Philip, who he says left us "a fair pattern of valiant and true knighthood".

"Grant unto him the assurance of thine ancient promise that thou wilt ever be with those who go down to the sea in ships and occupy their business in great waters," the dean prays.

The Archbishop of Canterbury personalises a prayer for the duke, adding thanks for "his resolute faith and loyalty, for his high sense of duty and integrity, for his life of service to the nation and Commonwealth, and for the courage and inspiration of his leadership".

"To him, with all the faithful departed, grant thy peace," the archbishop says.

After prayers - including the Lord's Prayer - are sung, the Dean of Windsor says the traditional collect from the Burial of the Dead service in the Book of Common Prayer, which has been used by the Church of England for hundreds of years.

It expresses the faith that those who believe in God the Father and in Jesus Christ "shall not die eternally" and the hope that "at the general resurrection in the last day, we may be found acceptable in thy sight".

Members of the Royal Family are seated in their own households during the service, in accordance with coronavirus regulations.

Brothers the Duke of Cambridge and Duke of Sussex are sitting opposite each other in St George's Chapel, with William joined by members of his family while Harry is seated alone. His wife Meghan was unable to travel from the US as she is pregnant.

They were able to walk together as part of the funeral procession before the service however, seen above alongside their cousin Peter Phillips.

Psalm 104 is set to music by William Lovelady, a contemporary composer and classical guitarist, who wrote the setting at the request of the duke.

It was previously sung at Prince Philip's 75th birthday.

"My soul give praise unto the Lord of heaven," the choir sings. "In majesty and honour clothed; The earth he made will not be moved, the seas he made to be its robe."

Now the Archibishop of Canterbury, Justin Welby, reads the second lesson from the Gospel of John, chapter 11, verses 21 to 27.

It recounts how Martha lamented the death of her brother Lazarus to Jesus. Jesus reassures her that her brother will rise again from the dead.

The archbishop reads Jesus' words to her: "I am the resurrection and the life; he who believes in me, though he die, yet shall he live, and whoever lives and believes in me shall never die."

The choir sings the Jubilate, whose words are taken from Psalm 100.

"O be joyful in the Lord, all ye lands," it says. "Serve the Lord with gladness, and come before his presence with a song."

The musical setting was written by Sir Benjamin Britten, one of the 20th Century's most significant British composers.

He wrote it for St George's Chapel in Windsor, at the request of the Duke of Edinburgh.

The ceremony is being conducted by the Dean of Windsor, David Conner, and Archbishop of Canterbury Justin Welby.

They received the coffin a little earlier when it arrived at the chapel before the start of the service.

The first lesson, read by the Dean of Windsor, is from the Book of Ecclesiasticus, chapter 43, verses 11 to 26.

"Look at the rainbow and praise its Maker," reads the dean.

The verses praise the power and beauty of God's creations in nature, perhaps reflecting the duke's environmental interests.

And the verses also reflect the duke's seafaring career.

"Those who sail the sea tell stories of its dangers, which astonish all who hear them; in it are strange and wonderful creatures, all kinds of living things and huge sea-monsters," reads the dean.

"By his own action he achieves his end, and by his word all things are held together."

In a service intended to honour the duke's naval career, the choir begins to sing perhaps the best-known hymn associated with seafaring, "Eternal Father, strong to save".

"O hear us when we cry to thee / For those in peril on the sea," is the famous refrain of each verse.

And it ends with the exhortation: "ever let there rise to thee / Glad hymns of praise from land and sea".

Now we hear the bidding, an invitation to prayer, said by the Right Reverend David Conner, Dean of Windsor.

"We are here today in St George's Chapel to commit into the hands of God the soul of his servant Prince Philip, Duke of Edinburgh," he says.

The dean says that "with grateful hearts" we remember the ways in which "his long life has been a blessing to us".

"We have been inspired by his unwavering loyalty to our Queen, by his service to the nation and the Commonwealth, by his courage, fortitude and faith," he says.

He tells the congregation that "our lives have been enriched" by the challenges he set, the encouragement he gave, "his kindness, humour and humanity".

The dean concludes the bidding with the words: "We therefore pray that God will give us grace to follow his example, and that, with our brother Philip, at the last, we shall know the joys of life eternal."

As the choir sings, the coffin is carried to its place on the catafalque, the raised platform where it will rest during the service.

Members of the Royal Family are led to their places in the Quire.

The choir are singing part of the Funeral Sentences by William Croft, biblical verses set to music by the 18th Century composer and organist.

The words include "I am the resurrection and the life" from the Gospel of John, chapter 11, verses 25 and 26, and "I know that my redeemer liveth" from the book of Job, chapter 19, verses 25 to 27.

The coffin has now entered the chapel ahead of the service.

It had paused on the steps while the silence took place.
