The son of Michael and Janet Onraet and the youngest of their three children, Onraet grew up in Surrey and is described as diminutive, softly-spoken and boyish-looking. Yesterday, his sister, Suzanne, 37, who lives in Wokingham, spoke admiringly of Davis, the man she was introduced to by her brother. "He is just running a business," she said, "and the fact is that he has been successful at doing so. There is no mystery beyond his success."
