The by-election would be an interesting one, considering the Bharatiya Janata Party (BJP) has said that it will field its candidate, said Tamizhisai Soundararajan, the party's State unit chief.
The temple town is expected to see a three-corner fight, as AIADMK, DMK and BJP are expected to field candidates. As the election date has been announced, the regional parties are expected to start negotiations with the major parties.
