Among star campaigners were BJP Prime Ministerial candidate Narendra Modi who held election meetings at Saharsa, Madhubani and Darbhanga on April 24, after he filed his own nominations from the Varanasi constituency, besides party colleague Sushma. Other campaigners were Chief Minister Nitish Kumar and RJD President Lalu Prasad.
No big leader from Congress campaigned for this phase of the elections. While BJP sought votes to make Narendra Modi the Prime Minister, the rival parties concentrated on stopping 'communal forces'. Polling would end at 4:00 PM in three Assembly segments of Mahisi in Madhepura and Simri Bhakhtiyarpur and Aluali in the Khagaria seat.
It would end at 6:00 PM in other places. Repoll would also be held in Sahebpur Kamal Assembly seat in Begusarai district. The repoll was necessitated after former minister Parveen Amanullah resigned from the Nitish Kumar cabinet and also gave up her Assembly seat to join AAP. Altogether 59,000 personnel of the central paramilitary forces and state police and two helicopters would be deployed during the elections.
