The move is one of a number of sweeping new changes aimed at modernising the ceremony, in addition to a female clergy, multilingual hymns being sung, and the participation of leaders of other faiths.
On Saturday, Brits, and those watching all over the word, will be invited to say the words: “I swear that I will pay true allegiance to your majesty, and to your heirs and successors according to law. So help me god”, in a proclamation that will dubbed a “homage of people”.
Previous coronations included a “homage of peers” and the change is aimed at reflecting a more progressive UK and Commonwealth.
But not everyone is impressed with the new “invite”, with some branding the attempt to “modernise” the monarchy as “offensive and tone deaf”.
Other new measures introduced include the King himself reciting a specifically-written prayer aloud, and a hymn sung in Welsh, Scottish Gaelic, English, and Irish.

The former traditional Homage of Peers previously saw a long line of hereditary peers kneel and make a pledge to the monarch in person, which often took significant lengths of time to get through, sometimes hours.
The new British sovereign will be crowned alongside his wife, Camilla, in a service at Westminster Abbey that will take place on the morning of May 6.

There will be two processions through the streets of the British capital on coronation day – one taking the King to be crowned and a larger parade back to Buckingham Palace after the historic service, where the monarch and members of the royal family will make a balcony appearance.
