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.

But this year, the Royal Family are out in force, with the Prince and Princess of Wales joining the King and Queen and other senior royals for the poignant service. Kate is wearing a striking dress by Catherine Walker and a matching hat by Gina Foster.
