It is Meghan’s first attendance at the Royal British Legion’s annual event at the Royal Albert Hall in London, which commemorates all those who have lost their lives in conflicts. This year also marks 100 years since the First World War ended.
The former actress married Prince Harry in May earlier this year and the couple have just completed their first royal tour of Australia.
Pregnant Meghan sported a black Stella McCartney wrap coat, while her sister-in-law Kate wore a Roland Mouret dress to mark the sombre occasion.
All of the royals sported multiple poppies to pay tribute to remember those who have lost their lives in war.
They were also joined by Prime Minister Theresa May and her husband Philip.
One notable absence was the Duke of Edinburgh, 97, who retired from public duties last year. He was part of the Royal Navy and served in the Second World War, before he married the Queen in 1947.
The audience watched performances from Sir Tom Jones, Sheridan Smith, Sir Bryn Terfel, McFly’s Tom Fletcher and Danny Jones, Sheku Kanneh-Mason and Harry and Meghan’s wedding choir Kingdom Choir, alongside the Central Band of the Royal Air Force and the Band of HM Royal Marines.
Earlier today, the Duke of Sussex attended the England vs New Zealand rugby match at Twickenham Stadium. Harry, who is Patron of England Rugby, aid a wreath on the pitch to commemorate those who have served and given their lives for their country.
Before the match, he met mascots Jack Davis and Max Garnett. Both are descendants of England captains who fought and lost their lives in the First World War.
Jack’s great-great grandfather, Lancelot (Noel) Slocock, captained England in his last game against Scotland in 1908. He died on the 9 August 1916 during the Battle of the Somme.
Max’s great-great uncle, Ronnie Poulton, was England’s captain from 1913-1914. Ronnie died in Belgium in May 1915. Soil from his war grave is buried next to the pitch at Twickenham.
Harry also met two players who are supported by England Rugby’s Injured Players Foundation, of which the Duke is also Patron.
The Queen and members of the Royal Family will attend the annual Remembrance Sunday service tomorrow morning at the Cenotaph, followed by the Armistice Service at Westminster Abbey in the evening.
