The Duchess of Cornall arrived at the Royal Albert Hall to pay tribute to all those who lost their lives in conflicts. The Queen was joined by the Prince of Wales, who earlier this week had to pull out of events because of a chest infection. The Duke and Duchess of Cambridge and the Duke and Duchess of Sussex sat with the Queen in the royal box at the annual Festival of Remembrance.

The event is the first time the Sussexes and Cambridges have appeared in public together since Harry and Meghan opened up about their struggles in an emotional television documentary. The Royal Family’s attendance at the annual Royal British Legion Festival of Remembrance comes every year. The event commemorates the 75th anniversaries of the great battles of 1944 and the collaboration and friendship of the British, Commonwealth and Allied armies who fought them.

The festival will also mark the 100-year anniversary of GCHQ and the role of the secret services. The event aims to pay tribute to the men and women from different nations, cultures, religions and communities who came together and stood shoulder to shoulder to defend Britain’s freedom. The Legion’s festival takes place every year on November 9.
