King Charles championed the royal family’s dedication to Commonwealth Day, calling for unity alongside Queen Camilla, Prince William and Kate Middleton at Westminster Abbey after he and Kate missed last year’s service due to their cancer treatments.

Last year, Princess Kate and King Charles did not attend the key royal event after they were diagnosed with cancer. The Palace announced that Charles had been diagnosed with a form of cancer back in February last year, while Kate went public with her diagnosis in a personal video message shared in March.

King Charles III and Catherine, Princess of Wales have attended the annual Commonwealth Day service, a year after both were forced to cancel because they were receiving cancer treatment. The event at Westminster Abbey on Monday celebrated the Commonwealth's "powerful influence for good in the world".
