"We will raise the issue of ballot papers in the meeting for fair and impartial elections. We want to make it clear that we do not consider EVMs as tamper proof," an opposition leader told IANS.

"Secondly, we would point out that the election expenses of political parties must also be limited along with the candidates," he added.

Although the EC in its official agenda of the meet released to the press has not mentioned simultaneous polls, the issue is likely to come up for discussion.

A majority of opposition parties have already told the Law Commission that they do not consider this proposal as practical or desirable.

The agenda for the meeting includes discussion on how to improve "accuracy, transparency and inclusiveness" of electoral rolls, measures to encourage enhanced representation of women in political process, issues related to expenditure ceiling for parties, timely submission of annual audited reports and election expenditure reports among other things.

Also on the agenda are alternative modes of voting for domestic migrants and absentee voters.
