Doron Avital, who headed the IDF's elite Sayeret Matkal unit when it captured Sheikh Mustafa Dirani in Lebanon, informed Kadima leader Tzipi Livni on Wednesday that he would seek a Knesset seat with the party. Avital, who holds a doctorate in logic and philosophy from Columbia University, headed a hi-tech management school at Tel Aviv University and now runs a venture capital firm. Livni said she was glad that Avital decided to contribute his experience to serve the party and the public.
