The vacancy for the constituency arose following the death of former Chief Minister Jayalalithaa on December 5 past year.
However, it was subsequently canceled by the Election Commission (EC) over allegations of bribing voters.
The last date for filing nominations is December 4 and withdrawal of candidature is on December 7. Out of 120 videos we received through WhatsApp, 100 are against T T V Dinakaran of AIADMK (Amma) and 20 are against the DMK candidate. But, after the Election Commission gave back the symbol to the EPS-OPS faction the dates for bypoll elections were announced by the Election Commission.
"We will win the bypoll with huge margin and prove that we are truly the successors of late Chief Minister and party leader J Jayalalithaa", former MP and spokesperson K C Palaniswamy told IANS.
Later the Sasikala faction broke into two with Palaniswami leading one.
DMK working president M.K. Stalin on Saturday sought to play down the allocation of the "two leaves" symbol to the ruling faction of the AIADMK, saying his party had defeated candidates of the ruling party even when its founder M.G. Ramachandran was alive.
Speaking to television channels on the by-election to Radhakrishnan Nagar, Tamil Nadu Congress Chief S Thirunavukkarasar said it will be a major test for the ruling AIADMK.
Jayalalithaa's niece J Deepa, who floated her own party MGR Jayalalithaa Deepa Peravai, contested the April 12 bypoll claiming the political legacy of her aunt. DMK fielded Ganesh as he was known in the constituency.
"Since earlier by election was deferred following cash distribution, the Commission should take concrete steps to prevent recurrence of such malpractices, KMDK General Secretary", E.R. Eswaran said.
The constituency came into prominence after Jayalalithaa chose to contest the seat in June 2015 after the Karnataka high court acquitted her in the disproportionate assets case.
