The Duchess of Edinburgh had a royal first as she paid her respects during the Armistice Service at the National Arboretum.
Sophie, 59, attended commemorations in Staffordshire, marking the two minutes silence across the UK and in Europe.
It was the first time the Duchess led the service solo, having previously been accompanied by her husband, Prince Edward, in 2020.
A different member of the royal family is usually chosen each year to represent the monarchy for the Armistice Service, with the Princess Royal and Sir Tim Laurence appearing at last year's event.
It comes the day after Sophie stood alongside the Princess of Wales on the balcony of the Foreign, Commonwealth and Development Office to watch the Remembrance Sunday service at the Cenotaph.
It marked Kate's fifth major public appearance of the year amid her gradual return to her royal duties after completing cancer treatment.

The poem ends with the verse:
"As the stars that shall be bright when we are dust,
Moving in marches upon the heavenly plain;
As the stars that are starry in the time of our darkness,
To the end, to the end, they remain."
