Leaders of as many as 22 Opposition parties met the Election Commission on Tuesday and demanded verification of VVPAT slips of randomly-selected polling stations before the counting of the votes polled in the Lok Sabha election begins on May 23.

They demanded that if any discrepancy is found during VVPAT verification, 100 per cent counting of the paper slips of VVPATs of all polling stations of that particular Assembly segment should be done and compared with the EVM results.

'We told the EC that the VVPAT machines should be counted first and if there is any discrepancy, then all of them in that segment should be counted,' Congress leader Ghulam Nabi Azad said after meeting EC officials.

Azad's party colleague Abhishek Singhvi said despite requests to the EC since months, the poll body has now said it will meet on Wednesday to discuss the issue.

'We are asking the EC to respect the mandate of people. It cannot be manipulated,' Telugu Desam Party's (TDP) N. Chandrababu Naidu said.

Bahujan Samaj Party leader Satish Chandra Mishra alleged that 'there is large-scale bungling relating to EVMs in Uttar Pradesh. We demand deployment of central forces'.

The Opposition parties raised concerns over the transportation of EVMs ahead of counting of votes and urged the EC to probe the issue. The Opposition parties are seeking transparency and fairness in the counting of votes and respecting the mandate of the people of the country.
