Rising to fame for the two corruption cases filed against him, Karti Chidambaram the top class businessman of the state and the son of the former Finance Minister P Chidambaram of the Congress Party will contest in Sivaganga constituency of Tamil Nadu. BJP has chosen to field H Raja from here. In 2014 Lok Sabha Elections, both these candidates faced a defeat letting Senthilnathan, the candidate representing All India Anna Dravida Munnetra Kazhagam win from here. While this is the second time that Karti Chidambaram contests from this constituency, he said, “I firmly believe the strength of the party and the alliance will help me win the Sivaganga seat.”
