The bypoll, to be held on June 12, was necessitated due to the death of CPI MLA S P Muthukumaran in a road accident on April 1.
Tamil Nadu Chief Minister Jayalalithaa campaigned for her party candidate Karthik Thondaiman on Saturday while DMDK chief and actor Vijaykant canvassed for his nominee Zakir Hussain today.
Nominating Thondaiman for the bypoll, Jayalalithaa had constituted a working group, which includes almost the entire state cabinet, to ensure the victory of the party nominee.
AIADMK's arch rival DMK along with other parties like CPI, PMK and MDMK have decided not to enter the polly fray.
