"The Prime Minister has been very active on this issue. This is an issue that needs a larger debate. It may look theoretically very easy to say something, but realistically there may be requirements for a Constitutional amendment too.
"It calls for a larger debate and all political parties must be involved. The larger question is of electoral reforms under the system. It is not having an election on a given date, but more important is electoral reforms," Congress spokesperson Tom Vadakkan said.
"These are larger issues. India is not a Madhya Pradesh or Gujarat, it is a large state. It is not an issue which can be sorted out by just saying that we have one election.
"Yes, I agree, financially it will be viable. But the viability becomes sensible only if it is feasible in real terms. And in real terms, it is a huge challenge which the Election Commission and the political parties in India must arrive at a consensus," he said.
"It has been proved now that Mayawati, who talked about 'goondaraj', will include Ansari and his friends in the BSP and we will see what BSP talks about 'goondaraj'," Vadakkan said.
