Ahdut HaAvoda
Unhappy with the move, several Mapam MKs left the party; Rostam Bastuni, Avraham Berman and Moshe Sneh established the Left Faction and Moshe Aram, Yisrael Bar-Yehuda, Yitzhak Ben-Aharon and Aharon Zisling set up Ahdut HaAvoda – Poale Zion, recreating the old party that had merged into Mapam. However, Hannah Lamdan and David Livschitz did not wish to join the new Ahdut HaAvoda party, so created the Faction independent of Ahdut HaAvoda.
