Authorities warned of traffic diversions ahead of the protest march and rally that will be led by Congress party leader Rahul Gandhi. The opposition says it expects hundreds of thousands of people to participate in what it says will be a major challenge to Prime Minister Narendra Modi and his Bharatiya Janata Party (BJP).

Opposition parties, student organisations and the youth-led Cockroach Janta Party have held near-daily demonstrations since last month demanding that Chief Election Commissioner Gyanesh Kumar step down over the voter list revision that critics say favour the BJP.
