The Election Commission has called a meeting on Friday in which around 40 political parties will take part. For the first time, the EC is going to hand over the EVM machine to parties, who claims tampering can be done with the EVMs. The EC is also planning to show live demonstration. Now, the toughest time starts for AAP leader Saurav Bhardwaj as he is going to accept tampering challenge and show the demo. BSP chief Mayawati was the first political leader to raise the issue of EVMs tampering.
