Prince William has said that he and Kate are "very happy" following the arrival of their daughter. The couple welcomed their second child this morning, although they have yet to confirm which name they have chosen for the baby. William emerged from the Lindo Wing at St Mary's Hospital this afternoon to collect son George and said that both mother and daughter were doing well. "We're very happy, thank you. I'm just going to pick up George," he told onlookers.
