Bengal’s electoral outcome will now be decided on 293 seats after EC cancelled Saturday the April 29 polling in south Kolkata’s Falta constituency, citing “electoral offences and subversion of the democratic process”.A repoll has been scheduled for May 21, with counting on May 24.This is first time in Bengal where a full assembly constituency will go to the polls after the declaration of results. In India, only Bihar had the precedence. EC said an inquiry into complaints found widespread tampering of EVMs at multiple booths.EC: Button tampering voids Falta mandateButtons were defaced with black masking tape and ink, affecting 60 of 285 polling stations — 21% of the constituency. These booths accounted for 53,967 voters (22.8% of the 2.36 lakh electorate).“This compromised the integrity of recorded votes and made it impossible to ascertain the mandate,” EC said, adding gaps in video footage meant similar tampering elsewhere in Falta could not be ruled out.Tension flared Saturday in Hasimnagar, a locality within Falta along the Hooghly river corridor, where villagers alleged threats from associates of TMC candidate Jahangir Khan. Police observer Ajaypal Sharma, a DIG overseeing Diamond Harbour subdivision on the city’s southern fringe, rushed to the area as residents complained of inaction.Security was stepped up with deployment of state police and central forces. EC later ordered the arrest of two of Khan’s aides, Izrafil Chokdar and Sujauddin Sheikh. The countermanding removes Falta from Monday’s count, tightening focus on the remaining seats that will determine the next govt.
