The 58-year-old took his place in the Royal Box at the Royal Albert Hall to remember those who fought in the First World War without the Duchess of York. Instead, the father-of-two stood with other members of the Royal Family such as the Queen, Prince Charles and wife Camilla, Prince Edward and wife Sophie, Meghan Markle and Prince Harry and the Duke and Duchess of Cambridge. Prime Minister Theresa May was also in the Royal Box with husband Philip.
Andrew, father of Princesses Eugenie and Beatrice who also did not attend, looked thoughtful as he watched on and paid his respects to the brave soldiers who served during the war.
