Soraya Khashoggi is the winner in the world's divorce settlement sweepstakes with an $800 million marital buyout from her Saudi arms dealer husband, Adnan Khashoggi, Forbes magazine reported Friday. Khashoggi, who was born Sandra Jarvis-Daly in England and lives in London, heads the list in spite of reports that Patricia Kluge, divorced wife of Metromedia tycoon John Kluge, may have received a $1 billion divorce settlement in 1990. Forbes claims untrue the report that Kluge, a onetime exotic dancer, gets the annual interest on $1 billion - roughly $80 million a year, and half of the 10,000-acre Charlottesville, Va., estate.
