Duke of Cambridge and Prince Harry visit Duke of Edinburgh in hospital Philip was forced to miss some of this week's Diamond Jubilee celebrations when he was admitted to hospital the day after the spectacular Thames Pageant on Sunday. On Wednesday he was visited by the Queen and the Duke of York, who said his father was in "good spirits" and feeling much better. It is feared that the river pageant, during which he stood aboard the royal barge for four hours with no access to a lavatory, could have exacerbated his condition. But it has emerged that he went carriage driving on Monday morning just hours before an ambulance was called to Windsor Castle. The Duke of Edinburgh was planning to celebrate his birthday privately and is not due to attend his next scheduled engagement until Tuesday, when the Queen will host a garden party on the Sandringham Estate to mark her Jubilee. It is also hoped that he will be able to accompany the Queen to the East Midlands on Wednesday for a two-day visit. The King's Troop Royal Horse Artillery is expected to fire a salute in London's Hyde Park to mark Philip's birthday, the Ministry of Defence said. The salute is fired every year to herald the occasion and the event is open to the public but not customarily attended by members of the royal family.
