New Delhi, May 19 (UNI) The Election Commission will announce its schedule for holding the Electronic Voting Machine (EVM) challenge at a media conference tomorrow. During the event, there will be a live demonstration of the EVM and Voter Verifiable Paper Audit Trail (VVPAT) in the foyer of Vigyan Bhawan where the conference will be held. The EC's decision to hold the challenge for tampering EVMs came following complaints by various political parties that these machines used in the recent assembly elections were tempered with. The EC has been saying that the machines were non tamperable. Last week, the EC held an all-party meeting here to discuss the issues related to allegations of malfunctioning of EVMs and proposed VVPATs and other electoral reforms. Chief Election Commissioner Nasim Zaidi had said the Commission would ensure total coverage of VVPAT in all future polls to Parliament and State Assemblies. Notably, soon after the results of the Uttar Pradesh assembly elections, Bahujan Samaj Party (BSP) chief Mayawati dismissed the Uttar Pradesh assembly election results and called for fresh polls alleging that tampering of EVMs was responsible for her party’s poor show. On May 9, during a one day special session of the Delhi Assembly, Aam Aadmi Party (AAP) MLA Saurab Bhardwaj demonstrated with a dummy, how EVMs were allegedly being tampered. Last month, a Congress-led delegation had submitted a memorandum on the alleged irregularities in EVMs to President Pranab Mukherjee. UNI RBE RSA ADG 1423
