“We, therefore, the lords spiritual and temporal of this realm, and members of the House of Commons, together with other members of Her late Majesty’s Privy Council, and representatives of the realms and territories, aldermen, and citizens of London and others, do now hereby, with one voice and consent of tongue and heart, publish and proclaim that the Prince Charles Philip Arthur George, is now, by the death of our late Sovereign of happy memory, become our only lawful and rightful liege lord, Charles III, by the grace of God, of the United Kingdom and Northern Ireland, and of his other realms and territories, King, head of the Commonwealth, defender of the faith, to whom we do acknowledge all faith and obedience with humble affection, beseeching God, by whom kings and queens do reign, to bless His Majesty with long and happy years to reign over us.
“God save the King.”
