NEW YORK (AFP) - Dominique Strauss-Kahn is expected to plead not guilty Monday to charges that he tried to rape a New York hotel maid, formally launching what could be a bruising campaign to clear his name. The former IMF chief faces arraignment before Judge Michael Obus in New York State Supreme Court on seven sex crime counts. Although Strauss-Kahn has repeatedly said through his lawyers that he is innocent, Monday is due to be the first time the silver-haired, 62-year-old tells the court himself.
