Before the service, their husbands King Felipe VI of Spain and King Willem-Alexander of The Netherlands were installed as Supernumerary or ‘Stranger’ Knights of the Garter.

They are chosen personally by the Queen to honour those who have held public office, who have contributed in a particular way to national life or who have served the monarch personally.

Supernumerary Knights are overseas monarchs appointed to the Order, and are in addition to the twenty-four knights or ladies.

The Duke of Edinburgh, the Duke of Kent, Princess Anne, the Duke of Gloucester, Princess Alexandra, Prince Andrew, Prince Edward and Prince William are all additional royal Knights and Ladies Companions.

The Duke of Cambridge received the honour in April 2008, becoming the 1,000th Knight of the Garter.

The Queen made the journey by car, wearing full ceremonial regalia, which include a dark blue velvet mantle embroidered with the Order of the Garter insignia and a red sash and black velvet Tudor style bonnets with ostrich and heron feathers.

Following the service, members of the Royal Family made their way back to the castle in carriages.

The Queen and the royals will be out together again this week at Royal Ascot.
