Justice Party (South Korea)

History

The party changed its name from "Progressive Justice Party" to "Justice Party" at the 2nd party congress on 16 July 2013. At the 4th party congress on 22 November 2015, the party officially merged with extra-parliamentary groups: Preparatory Committee for the People's Party (2015), Solidarity for Labor Politics, and Jinbo Plus, which composed of members defected from the Labor Party, after motions to merge the party with the Justice Party failed.

After the merger, Na Gyung-che, leader of the Jinbo Plus, and Kim Se-kyun, leader of Preparatory Committee for the People's Party, were elevated to co-leadership role, while Sim Sang-jung remained as a standing party leader. Kim Se-kyun stepped down from the co-leadership in September 2016.

In the legislative election held in April 2016, the party increased their seat total by one, with the election of Roh Hoe-chan to the Seongsan constituency in the city of Changwon. The party polled 7.2% in the party list ballot, returning in total, six legislators to the National Assembly.
