台灣團結聯盟
Former president Lee and estranged politician James Soong and their followers broke ranks with the Kuomintang shortly after the coming to power of the DPP, having positioned themselves as supporters of Taiwan independence. This split led to the formation of the Taiwan Solidarity Union, which unlike the modern DPP, actively advocates Taiwan independence. The TSU has attracted former members of the DPP dissatisfied with that party's increased distance from the independence movement.
