The Queen was dressed in black (aside from the red poppies pinned on her lapel) as she watched her son, Prince Charles lay the first wreath of red poppies on the Cenotaph in Whitehall.
This is the third time the Prince of Wales has led the country on a Remembrance Day service.
The last time the Queen performed the duty was in 2016, according to Express.
The Duchess of Sussex stood on a separate balcony to Kate, Camilla and the Queen as she did at her first Remembrance Day service last year. At the time, royal fans were confused by her position.
However, the placement wasn't necessarily a slight against the 38-year-old, as there were practical limitations that led to her separation from the other members of the royal family.
"As the balconies of each window are small, it’s nearly impossible to fit more than three or four women on each – and although Meghan didn’t join her family members, she was given a very important position of her own," People reporters Maria Pasquini and Simon Perry said at the time.
Sunday's Remembrance Day service is the final Remembrance Service that the royal family will attend together this year.
Prince Edward, Duke of Kent will attend the National Memorial Arboretum Armistice Day Service in Staffordshire on Monday to conclude the week.
