Noubaiese Socialist Workers' Party

1951-1992
The party was formed as a forced merger between the Eastern branches of the Socialist Party and the Noubaiese Communist Party, although it's often regarded as an incorporation of the former into the latter.

In preparation for the reunification of the country in 1992, the party was disbanded, with a majority of its members switching their affiliation to the Left Front, although a few splinter factions defected to the Noubaiese Communist Party.
