- Observations: Wihda or the PDUP was originally the Jordanian branch of George Habash's Popular Front for the Liberation of Palestine and split off in 1990 to form a separate Jordanian political party. The party is critical of Jordan's lack of political reform, particularly of its electoral law and as a result boycotted the 2010 and 2013 elections.
