The Maha Vikas Aghadi - thumped last week in the Maharashtra election - is planning a national protest against the credibility of EVMs, or electronic voting machines, which it blames for its defeat.
The MVA - fronted by the Congress and the Shiv Sena and NCP factions led by Uddhav Thackeray and Sharad Pawar - also plans to move the court to return to ballot papers.
