After the Prince of Wales had to cancel his appearance to attend a service to celebrate the life of King Constantine of Greece, questions were immediately asked if the last-minute decision was linked to the Princess of Wales' recovery from her abdominal surgery. However, it was quickly confirmed that Kate - who returned home a month ago after spending two weeks in the London Clinic - was not the reason for the cancellation.There were concerns that William - who was due to honour the memory of his godfather, King Constantine - and his sudden withdrawal from the event had something to do with his wife's health.
