Britain revelled in the coronation of King Charles III on Sunday as it staged a star-studded concert watched by 20,000 people at Windsor Castle and millions more across the country and world.

Charles, 74, and Queen Camilla, 75, watched on from a royal box in the grounds of the castle west of London, as Lionel Richie, Katy Perry and British band Take That topped the bill of performers.

Screens erected nationwide broadcast the televised event -- featuring a 70-piece orchestra, choirs and several unique dramatic performances -- to communities, while organisers said it would also be seen in over 100 countries.

Amid the music and video message tributes from an array of public figures, Prince William took to the stage to pay tribute to his father the day after he was formally crowned king.

Noting his late grandmother, Queen Elizabeth II, was "up there, fondly keeping an eye on us", William added she would be "a very proud mother".
