Rare image of young, carefree Queen with corgis, sister and much-loved dad George VI
A third rare image of the Queen has been released as celebrations to mark the monarch's 90th birthday continued with a star-studded show in the grounds of Windsor Castle.
The photo, seen publicly for the first time, shows a young, smiling, Princess Elizabeth with her sister and father. Princess Margaret and George VI each hold one of the Queen's beloved corgis.
The colour photo was released a day after two black and white images from archive footage were published ahead of last night's gala show which looked back on the Queen's long reign, and featured an array of celebrities including Gary Barlow and Kylie Minogue.
One of the photos shows a young Princess Elizabeth ready to go for a swim with her father.
Arms outstretched and with a beaming smile, the future Queen stands alongside George VI on the edge of an outdoor swimming pool, ready to take a dip. In another she is seen looking intently as a bird rests on her arm.
Ant and Dec hosted last night's programme, featuring more than 1,500 performers from singers Katherine Jenkins and Dame Shirley Bassey, to actors Imelda Staunton and Dame Helen Mirren.
It covered the Queen's early years, teenage life, the Second World War and her Coronation to the present day. Her love of horses was represented by more than 900 of the animals in the celebration.
