Labor party Chairman Amir Peretz announced late Sunday night that he would oppose the addition of Yisrael Beiteinu to the coalition when the Labor party central committee convenes on Tuesday to decide whether Labor should quit the government. While Peretz said he appreciated Yisrael Beiteinu Chairman Avigdor Lieberman's willingness to the join the government without changing the governing guidelines, he said he still could not accept sitting in the government with a party with whose views he completely objects.
