The former president's decision to address the Rashtriya Swayamsevak Sangh's (RSS) Shiksha Varg and attend a parade by Sangh workers on June 7 has raised quite a few eyebrows in the political circle.
The visit had also not gone down well with the Congress leaders initially, though they heaped praise on Mukherjee's speech at the event.
Responding to a query on the proposed 'one nation one election', Ali said the JD(S) and several other opposition parties were opposed to the idea.
"It is not possible as each state has its own issues," he said.
The JD(S) leader also demanded that elections be conducted through ballot papers as he said that several parties have raised fingers at the credibility of electronic voting machines (EVMs).
