Prince William invokes late queen in tribute to King Charles after coronation

The late Queen Elizabeth would be "very proud" of King Charles on his coronation, his son William said on Sunday as he celebrated his father at a concert at Windsor Castle, and Britons held thousands of street parties in the king's honour.

Amid pomp and pageantry, Charles and his wife Camilla were crowned at London's Westminster Abbey on Saturday in Britain's biggest ceremonial event in 70 years.

A Buckingham Palace spokesperson said Charles and Camilla were "deeply touched by the events of yesterday" and "profoundly grateful both to all those who helped to make it such a glorious occasion and to the very many who turned out to show their support."

Charles and Camilla and other senior royals joined an audience of 20,000 members of the public and invited guests for the "Coronation Concert" at Windsor, the king's palace to the west of London.

"As my grandmother said when she was crowned, coronations are a declaration of our hopes for the future. And I know she's up there, fondly keeping an eye on us, and she'd be a very proud mother," Charles' heir, William, said at a speech at the evening concert, to huge cheers.

William paid tribute to his father's service and others who serve, including teachers and hospital workers, many of whom have been striking in recent months.

Among the performers were singers Lionel Richie, Katy Perry and Andrea Bocelli, pop group Take That and pianist Lang Lang, while Hollywood actor Tom Cruise and Winnie the Pooh also featured.

Charles was shown waving a mini union flag from the royal box and laughing at jokes, including one that labelled Charles, a keen painter, as the "artist formerly known as Prince".

The festivities included a "Lighting up the Nation" event, with projections and laser displays illuminating landmarks and areas of natural beauty across the country.
