The Duke of Edinburgh, who will turn 91 on Sunday, June 10th, continues to recuperate in King Edward VII Hospital in London from a bladder infection, an ailment that prevented the Duke from participating in the final days marking the festivities of Queen Elizabeth II’s Diamond Jubilee. Buckingham Palace has said that Prince Philip has “improved considerably” and “is in good spirits.” Members of the royal family have been visiting the Duke in the hospital. On June 5th, the Earl and Countess of Wessex and their children, Louise and James, were there. The Earl had told reporters that his father watched the Jubilee festivities on television and that he was “feeling a lot better.” The Queen, after attending a Commonwealth Heads of Government Lunch on June 6th, then paid her husband a nearly hour long visit. Soon afterwards, the Duke of York visited his father and told reporters that “he’s mending very well.” No word yet on when the Duke of Edinburgh will be released from hospital.
