Prince Philip, Queen Elizabeth's husband, released from hospital after heart surgery

Exactly one month after entering the hospital "feeling unwell," Prince Philip was finally heading home on Tuesday. Images captured Tuesday morning showed the Duke of Edinburgh leaving a London hospital in a black BMW. 

"The Duke of Edinburgh has today been discharged from King Edward VII's Hospital and has returned to Windsor Castle," Buckingham Palace said in a statement. "His Royal Highness wishes to thank all the medical staff who looked after him at both King Edward VII's Hospital and St Bartholomew's Hospital, and everyone who has sent their good wishes."  The 99-year-old husband of Queen Elizabeth II was admitted to the private King Edward VII Hospital in mid-February as a "precautionary measure" for "observation and rest." The palace later said he was being treated for an infection.
