Meanwhile, EVMs are being kept ready for the bypoll, where 29 candidates, including AIADMK's S Valarmathi, DMK's N Anand, BJP's M Subramaniam and CPI-M's K Annadurai, are in the fray.
The byelection was necessitated to fill the vacancy caused by the disqualification of AIADMK chief Jayalalithaa following her conviction in a diproportionate assets case.
