Thoothukudi Lok Sabha seat will witness a high profile contest between DMK leader Kanimozhi and state BJP chief Dr. Tamilisai Soundararajan.
For both leaders it will be their first direct election. Kanimozhi, who has been elected twice to the Rajya Sabha, has been grooming the constituency, spending a large portion of her MPLAD funds there.
BJP national secretary H. Raja, known for his inflammatory speeches, will try his luck again from Sivaganga constituency. In 2014 as the candidate of the NDA, he had finished third ahead of Karti Chidambaram of the Congress. Karti is likely to be the UPA candidate this time too.
Union Minister of state Pon Radhakrishnan will seek reelection from Kanyakumari and will face a Congress candidate.
C. P. Radhakrishnan has been fielded again from Coimbatore since he had won twice in 1998 and 1999 and finished a strong second in 2014.
For Ramanathapuram seat, former AIADMK leader Mini Nainar Nagendran, who joined the BJP a year ago, has been fielded and will take on the IUML candidate.
