Sarathkumar launched his own political party the All India Samathuva Makkal Katchi on 31 August 2007. Sarathkumar said: "We are disillusioned by the Dravidian parties, which had done little to develop the state despite being in power for four decades". Just before 2011 Assembly elections, Sarathkumar joined the AIADMK alliance and his party was allotted two seats. His party contested as part of the AIADMK alliance and won in two assembly constituencies – Tenkasi and Nanguneri. Sarathkumar won from Tenkasi and Ernavur A. Narayanan won from Nanguneri. In January 2016, Ernavur A. Narayanan has been expelled from the party for not abiding by the party rules and indulging in anti-party activities. In the 2016 Assembly elections, Sarath Kumar lost in Tiruchendur Constituency to DMK Candidate Anitha R. Radhakrishnan. In November 2017, Sarathkumar said in an interview for The Hindu : "For the last 10 years, I have been closely associated with AIADMK. In fact, I have even been identified as the party’s propaganda secretary. Though I don’t regret this identification, my party couldn’t grow. Now, I want to focus on my party and be seen as a possible Chief Minister candidate".
