LONDON, June 18: A smiling Prince Philip, the 92-year-old husband of Britain’s Queen Elizabeth, left hospital after 11 days yesterday, slightly earlier than expected, following an operation on his abdomen. Looking sprightly and in good spirits, the prince walked unaided out of the London Clinic, shaking hands with the staff and waving to onlookers outside, before getting into his car to be driven to Windsor Castle, west of London.
