In 1990 Shimon Peres tried to form an Alignment-led coalition in a move that became known as "the dirty trick", but failed to win sufficient support. Eventually Shamir formed the twenty-fourth government on 11 June 1990, with a coalition encompassing Likud, the National Religious Party, Shas, Agudat Yisrael, Degel HaTorah, the New Liberal Party, Tehiya, Tzomet, Moledet, Unity for Peace and Immigration and Geulat Yisrael. Tehiya, Tzomet and Moledet all left the coalition in late 1991/early 1992 in protest at Shamir's participation in the Madrid Conference.
