Coronation: Public asked to swear allegiance to King Charles

People watching the Coronation will be invited to join a "chorus of millions" to swear allegiance to the King and his heirs, organisers say.

The public pledge is one of several striking changes to the ancient ceremony revealed on Saturday.

In a coronation full of firsts, female clergy will play a prominent role, and the King himself will pray out loud.

The Christian service will also see religious leaders from other faiths have an active part for the first time.

The Coronation on Saturday will be the first to incorporate other languages spoken in Britain, with a hymn set to be sung in Welsh, Scottish Gaelic and Irish Gaelic.

Despite changes designed to reflect other faiths, the three oaths the King will take and form the heart of the service remain unchanged, including the promise to maintain "the Protestant Reformed Religion".

Full details of the Westminster Abbey service - the theme of which is "called to serve" - have been published by Lambeth Palace.

The Archbishop of Canterbury said it would "recognise and celebrate tradition" as well as contain "new elements that reflect the diversity of our contemporary society".

The public will be given an active role in the ceremony for the first time, with people around the world set to be asked to cry out and swear allegiance to the King.

This "homage of the people" replaces the traditional "homage of peers" where hereditary peers swear allegiance to the new monarch. Instead everyone in the Abbey and watching at home will be invited to pay homage in what Lambeth Palace described as a "chorus of millions".

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 forever."

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."
