台湾団結連盟
The Taiwan Solidarity Union (TSU) is a left-wing progressive party characterised primarily by its Taiwanese nationalism and derives its membership from both the Kuomintang's former moderate and Taiwan-oriented fringe and DPP supporters disgruntled by the party's moderation on the question of Taiwanese sovereignty. Its progressive character is questionable, although it is part of the DPP's pro-Taiwan independence Pan-Green alliance. The TSU lost all of its seats in the 2016 elections.
