The Other Prince William tells the tragic story of Prince William of Gloucester, the Queen's cousin whose good looks and playboy lifestyle made him the idol of a young Prince Charles. Prince William, a pageboy at the Queen's wedding and fourth in line to the British Throne at the time, was described as the most dazzling Royal of his generation. He embarked on a forbidden love affair with Zsuzsi Starkloff, a glamorous divorcee, model and former air hostess which was to end in disaster. In her first televised interview, Zsuzsi Starkloff will tell the story of their forbidden relationship and the disapproval it caused behind the doors of Buckingham Palace, still reeling from the scandal of Edward's abdication for the love of Mrs Simpson.
