Clarence House has released a new image of Camilla, Duchess of Cornwall to mark her 70th birthday, shot by veteran photographer Mario Testino.

The image, taken in the Morning Room at Clarence House, sees The Duchess wearing an embroidered navy dress coat alongside The Prince of Wales. Testino commented 'I'm honoured to document Their Royal Highnesses The Prince of Wales and The Duchess of Cornwall on this very important date. I first photographed The Duchess after her wedding to The Prince on a commission from British Vogue in 2006, and discovered a kind and beautiful person with a wonderful sense of humour. Doing this latest assignment to celebrate Her Royal Highness's 70th birthday is a true honour'.
