The Duke and Duchess of Cambridge glowed with pride as they left the hospital with their new baby daughter - just 12 hours after arriving at the Lindo Wing and ten hours after giving birth.

The couple emerged on the steps outside St Mary's Hospital in west London shortly after 6pm and the world was given a brief glimpse of the new princess, who was wrapped in a white blanket and held tenderly in her mother's arms.

The newest Royal, whose name is yet to be announced, was born at 8.34am today weighing 8lbs and 3oz - less than three hours after the Duchess was admitted to hospital.

Kate looked remarkably fresh in a yellow floral Jenny Packham dress, with her hair and make-up freshly done, as the pair stood for a few minutes proudly showing off their second child and waving for the cameras.
