Late TV presenter Jimmy Savile, who may have abused as many as 300 children, was so close to Prince Charles that he advised him on the appointment of one of his most senior aides. In an indication of the power and privilege extended to Savile by the royal family, Charles asked the DJ and television presenter for advice before selecting Sir Christopher Airy to be his private secretary in 1990. The revelation shows the close friendship between the heir to the throne and the television presenter, who the prince grew to rely on in the late 1980s and early 1990s. The two men became unlikely friends after meeting in the late 1970s while working with wheelchair sports charities. Former palace aides have described how Savile inveigled his way into the royal family, dropping in to see Charles when it suited him. While the prince seemed amused by Savile's eccentricity, Diana, Princess of Wales seemed more cautious. Despite this, the friendship between Charles and Savile grew closer over the years, in part due to Savile's charity work. In 1990, Charles brought Savile into his home in an attempt to help smooth over his relationship with Diana when it became clear their marriage was beginning to fall apart. Charles even dispatched the presenter to help the Duchess of York keep a low profile as her marriage to his brother Prince Andrew deteriorated. Savile's tasks also included helping Charles pick his private secretary. After consultation with Savile, Airy was appointed private secretary and treasurer to the prince and Diana. When Savile died last year, Charles led the tributes to him, saying his death had left him incredibly saddened".
