The polling for three Tamil Nadu assembly constituencies — Thirupparankundram, Aravakkurichi and Thanjavur — and the lone Nellithope constituency in Puducherry began at 7 a.m. .
In Tamil Nadu, nearly 7.54 lakh voters are expected to exercise their vote and decide the fate of 81 candidates in the fray in the three constituencies.
In Thanjavur, the AIADMK’s M. Rengasamy is pitted against the DMK’s Anjugam Bhoopathy.
In Thirupparankundram, the by-election has been necessitated by the death of AIADMK’s legislator S.S. Seenivel.
While there are other parties in the contest, the contest is mainly between the AIADMK and the DMK in Tamil Nadu.
In Puducherry’s Nellithope, Congress leader V. Narayanasamy is contesting against AIADMK nominee Om Shakthi Segar.
The counting of votes will be held on November 22.
