PARIS, Apr 2: Former French first lady Carla Bruni took up a passionate defense of her husband Nicolas Sarkozy on Wednesday, saying it was unthinkable he could have tricked an old lady out of millions of euros. In a blitz of interviews with French media, Bruni said a formal investigation of the ex-president opened last week for allegedly exploiting the mental frailty of 90-year-old L’Oreal heiress Liliane Bettencourt was causing her great pain.
