Shas is a Haredi religious political party in Israel. Founded in 1984 under the leadership of Rabbi Ovadia Yosef, a former Israeli Sephardi chief rabbi, who remained its spiritual leader until his death in October 2013, it primarily represents the interests of Sephardic and Mizrahi Haredi Jews.

Meretz is a left-wing political party in Israel. The party was formed in 1992 by the merger of Ratz, Mapam and Shinui, and was at its peak between 1992 and 1996 when it had 12 seats. It currently has no seats in the Knesset, following its failure to pass the electoral threshold in the 2022 elections, the first time it failed to win seats in the Knesset since the party's inception.
