Everyone in Britain will be asked to swear allegiance to the King out loud during his Coronation today.
Charles’s ceremony has been modernised to include the first ever Homage of the People - a sentence that everyone in the country and millions watching around the world will be asked to say, to show commitment to the new monarch.
Lambeth Palace said it was hoped the significant change to the historic service will result in a “great cry around the nation and around the world of support for the King” from those watching on television, in pubs, online or gathered in the open air at big screens.
It replaces the traditional Homage of Peers in which a long line of hereditary peers knelt and made a pledge to the monarch in person.
The liturgy – words and actions of the Coronation service – have been revealed, having been decided upon in close consultation with the King, the Archbishop of Canterbury and the Government.
The new Homage of the People was introduced to allow “a chorus of millions of voices” to be “enabled for the first time in history to participate in this solemn and joyful moment”, Lambeth Palace said.
The Archbishop will call upon “all persons of goodwill in The United Kingdom of Great Britain and Northern Ireland, and of the other Realms and the Territories to make their homage, in heart and voice, to their undoubted King, defender of all”.
The order of service will read: “All who so desire, in the Abbey, and elsewhere, say together:
I swear that I will pay true allegiance to Your Majesty, and to your heirs and successors according to law. So help me God.”
It will be followed by the playing of a fanfare.
The Archbishop of Canterbury will then proclaim “God Save The King”, with all asked to respond:
“God Save King Charles. Long Live King Charles. May The King live for ever.”
A spokesman for Lambeth Palace, the Archbishop’s office, said: “The Homage of the People is particularly exciting because that’s brand new.
“That’s something that we can share in because of technological advances, so not just the people in the Abbey, but people who are online, on television, who are listening, and who are gathered in parks, at big screens and churches.
“Our hope is at that point, when the Archbishop invites people to join in, that people wherever they are, if they’re watching at home on their own, watching the telly, will say it out loud – this sense of a great cry around the nation and around the world of support for the King.”
King Charles will be the first man to wear the St Edward's Crown since his grandfather, George VI, in 1937
The words printed in the service are for “everyone to share in”, the spokesperson said.
Before the Homage of the People, the Archbishop of Canterbury will pay homage representing the Church of England, followed by the Prince of Wales – performing what is the only Homage of Royal Blood.
Just like his grandfather Prince Philip, the Duke of Edinburgh did for his wife Elizabeth II at her Coronation, William will kneel before the monarch, place his hands between his father’s and vow to be his “liege man of life and limb”.
He will say: “I, William, Prince of Wales, pledge my loyalty to you and faith and truth I will bear unto you, as your liege man of life and limb. So help me God.”
The symbolic act means the heir to throne, as ‘liege man’ to the King, has a mutual obligation to the monarch.
In the past, other dukes of royal blood would pay homage, but this time, with only William taking part from the royal family, it removes the need for the controversial Dukes of Sussex and York to undertake this role.

The removal of the role of hereditary peers - as well as Harry and Andrew - also has the benefit of helping to reduce the length of the service, which is now two hours instead of around three as it was at the late Queen’s Coronation.
William has another duty during the service.
He will enter the Coronation theatre earlier in the ceremony in the investiture segment and help clothe the King in the robe royal, also known as the mantle, ahead of the crowning.
William will join Baroness Merron, former Board of Deputies of British Jews chief executive, and help bishops to lift the “robe of righteousness” on to his father.
The robe represents what the King, as sovereign, has been given by God.
Charles III will then wear the £5bn St Edward's Crown - the most important and sacred of all the Royal jewels - when he is officially declared as the King.
The crown, which is only used during Coronation ceremonies, was made in 1661 and initially belonged to Edward the Confessor.
Weighing nearly 5lbs, it is made of solid gold and is usually kept at the Tower of London as part of the Crown Jewels collection.
