Duchess of Cambridge bursts into hysterics as she grabs stumbling Sophie during the Queen's carriage parade at Royal Ascot

Sophie Wessex, 52, and Kate, 35, laughed uproariously (top right) as the Countess took a tumble during the Queen's carriage parade at Royal Ascot after losing her balance. Sophie almost fell on top of Kate (left) who luckily shot her arms out just in time to break her fall. Luckily the pair saw the funny side as Kate helped to steady her before stepping out into the parade ring (right). The Duchess opted for bespoke lace Alexander McQueen while Sophie opted for the same colour as the Queen (inset) who was also resplendent in green. It was a family affair for the royals with Princess Eugenie and her sister Beatrice also in attendance, along with Prince Charles and Camilla.
