HARTFORD, Conn. AP – A lawyer for a 36-year-old Swedish countess who’s divorcing United Technologies Corp. Chairman George David tried to cast doubt on her estranged husband’s credibility by accusing him of lying in previous testimony about sex with his mistress.

William Beslow, an attorney for Marie Douglas-David, made the allegation Thursday as he questioned the 67-year-old multimillionaire in a Connecticut courtroom during the second day of their divorce trial, which lawyers in the case say is one of the most costly in state history.
