The Duke and Duchess of Sussex have joined the nation and the monarchy in celebrating the Queen's official birthday at the Trooping the Colour ceremony.
Meghan experienced the pomp and pageantry of the event for the first time when she arrived on Horse Guards Parade with Harry in a carriage, along with the Queen's cousin the Duke of Kent.
The couple were greeted by the sight of hundreds of Guardsmen in their scarlet tunics and bearskins lined up on the parade ground - Henry VIII's former jousting yard - as the event began.
The duke and duchess, who married exactly three weeks today, travelled from Buckingham Palace along the Mall to cheers from royal fans gathered in the famous London thoroughfare.
The Duchess of Cornwall and Duchess of Cambridge were in another carriage while a third carried Princesses Beatrice and Eugenie, the Countess of Wessex and her daughter Lady Louise.
Trooping the Colour is a ceremonial spectacle that brings together prestigious regiments and the families of the serving men and women in celebration of the monarch's official birthday.
Stands lining Horse Guards were filled with the wives, girlfriends and parents of the servicemen who when not performing ceremonial duties are fighting soldiers.
Meghan, Harry and the other members of the royal family took their place in Wellington's former office which overlooks the parade ground.
The Duchess of Sussex wore a dress by Carolina Herrera and a hat by Philip Treacy, while Kate wore a dress by Alexander McQueen and a hat by Juliette Botterill.
Camilla wore a pale blue silk dress and coat by Bruce Oldfield and a hat by Philip Treacy.
The Queen soon made her entrance onto Horse Guards in an Ascot Landau after making her journey from her famous London home Buckingham Palace.
Her procession was accompanied by a Sovereign's Escort of the Household Cavalry, made up of Life Guards and Blues and Royals, in their silver and gold breastplates and plumed helmets.
The 7,500 guests seated in stands lining the parade ground stood as a mark of respect as the monarch arrived and began inspecting the massed ranks of the troops.
The Duke of Edinburgh, who celebrates his 97th birthday on Sunday, has retired from official public duties and did not attend.
But the Queen was accompanied by the royal colonels, all on horseback: Prince of Wales, Colonel of the Welsh Guards, the Princess Royal, Colonel of the Blues and Royals, and the Duke of Cambridge, Colonel of the Irish Guards.
Also riding in the ceremony for the first time was the Duke of York in his new role as Colonel of the Grenadier Guards.
Among the guests was Defence Secretary Gavin Williamson, the Prime Minister Theresa May normally attends but is at a G7 meeting of world leaders in Canada.
