The choir sings a rousing rendition of Handel's Zadok the Priest.
It includes the words "God save the King".
We're now in the most sacred part of the service.
The King's ceremonial robe is removed and he sits in the Coronation Chair to be anointed. It’s a way of emphasising the spiritual status of the sovereign, who is also the head of the Church of England.
A screen is arranged around the chair to conceal the King from view.
Some more pictures for you while the choir sings.
Prince Louis has been spotted taking in the service alongside his sister, Princess Charlotte.
Next, the anointing stage.
First, we hear the choir sing in English, Welsh, Gaelic, and Irish.
As Welby continues his address, let's have a look at some new snaps.
These pictures have just come through of the Prince and Princess of Wales, their children and other senior royals watching the ceremony.
"Service is love in action," Welby continues, as he delivers his sermon.
He pays tribute to 400 young charity workers who are watching the service from St Margaret's Church, next door to Westminster Abbey, who he labels "extraordinary".
"We are here to crown a king, and we crown a king to serve," says Archbishop of Canterbury Justin Welby, as he starts to deliver his sermon.
Now for another original composition by Debbie Wiseman.
"Alleluia, alleluia," sing the Ascension Choir - who sing their praises to the King.
It's the first time during a coronation service that we've heard gospel music.
We're hearing Dame Sarah Mullally reading the Gospel.
A short while earlier, we saw King Charles arrive for his Coronation, with his pages of honour. You can watch the historic moment below.
We're now hearing a new composition from Debbie Wiseman, which was created for this service.
We're now hearing more prayers and readings, before the next stage.
UK Prime Minister Rishi Sunak also makes an appearance - reading from the Epistle to the Colossians, from the New Testament.
As we listen to the choir, let's take a look back at the moment King Charles III arrived at Westminster Abbey. He walked up the aisle before taking his seat at the top of the church with Camilla, the Queen Consort.
For those following along at home or out and about, you can read the full order of service here.
After some words from the King, he returns to sit in the Chair of Estate.
The choir sings Gloria in Excelsis Deo (meaning Glory to God in the Highest).

It’s also worth noting how intricately this ceremony been put together, like a huge tapestry in its own right.
For instance, there were debates about the King’s oath stating his specific role as upholder of the “Protestant succession to the throne”.
But, soon after the King makes that pledge the choir sings a piece in Latin by William Byrd, from a setting of the mass used by 16th Century Catholics who had opposed the doctrine of the Church of England.
And the oaths are framed by a wider recognition of people of “all faiths and beliefs”.
It’s a service full of balancing acts and subtle symbols.

There has been a deliberate attempt to make this a more multifaith and diverse ceremony, alongside what is essentially a Christian church service.
There are representatives of the Muslim, Jewish, Sikh and Buddhist communities – and the prime minister reading out a Bible reading is Rishi Sunak, a Hindu.
Black and Asian people will have prominent roles within the ceremony, including as public figures and as part of the clergy. Women bishops will be participating for the first time in a thousand years of Coronations.
There are words in Welsh, Scottish, Irish Gaelic and a Byzantine chant in Greek, as a nod to the King’s late father, Prince Philip.
The Archbishop of Canterbury acknowledges the multiple faiths observed in the UK by saying the Church of England "will seek to foster an environment in which people of all faiths may live freely".
Welby then administers the Coronation Oath - a legal requirement.
He asks King Charles to confirm that he will uphold the law and the Church of England during his reign.
The King places his hand on the Holy Gospel and pledges to "perform and keep" those promises.
He also takes a second oath - the Accession Declaration Oath - stating that he is a "faithful Protestant".
Here are some of the latest pictures coming from inside Westminster Abbey:
We’re hearing 12 newly-commissioned pieces of music throughout the service - written by composers from across the UK and the Commonwealth, and personally chosen by the King.
There are several stages to the service, which is expected to last a little under two hours.
In the first stage - the recognition - King Charles is presented to "the people", in a tradition dating back to Anglo-Saxon times.
