Prime Minister Ariel Sharon last night rejected a demand made by Ministers Benny Elon and Avigdor Lieberman (NationalUnion/Yisrael Beitenu) that he halt negotiations with the PLO that include talk of establishing a Palestinian State. In a letter to Sharon, Elon and Lieberman demanded that the issue of a Palestinian State first be brought for approval in the cabinet. Contrary to Sharon\'s initial rejection, government aide Gideon Sar later told ministers Elon and Lieberman that in fact no final decision had been made regarding their request.
