British longest reigning monarchy, Queen Elizabeth II have released an official portrait to mark her 90th birthday.
The photo shows the Queen with her son Prince Charles in the White Drawing Room at Windsor Castle.
Previously unpublished, it was taken before the final night of celebrations at the Royal Windsor Horse Show in May.
Fashion photographer Nick Knight, who took the photo, said he had wanted to create something that showed “warmth, humanity… strength and tradition”.
The Queen, who last year became Britain’s longest-reigning monarch, turned 90 years old in April.
