The ceremony was structured around an Anglican service of Holy Communion. It included Charles taking an oath, being anointed with holy oil, and receiving the coronation regalia, emphasising his spiritual role and secular responsibilities.^[a] Representatives of the Church of England and the British royal family declared their allegiance to him, and people throughout the Commonwealth realms were invited to do so. Camilla was crowned in a shorter and simpler ceremony. After the service, members of the royal family travelled to Buckingham Palace in a state procession and appeared on the palace's rear and front balconies. Several changes were made from past coronations, including a shorter runtime when compared to Elizabeth II's and alterations to reflect the United Kingdom's multiple faiths, cultures, and communities. The event reached a peak television audience of 20.4 million in the UK, making it the country's most-watched broadcast of 2023. Globally, it attracted an audience of two billion people across 125 countries.
