Millions poured into polling centres across 12 states Thursday in the sixth round of general election to pick 121 members to the Lok Sabha, officials said.
An estimated 25 percent of the 197 million people eligible to vote Thursday had exercised their franchise in the first five hours after balloting began at 7 a.m. in 225,387 centres, the Election Commission said.
The polling began on a dull note but picked up pace as the hours rolled by, officials said, barring in one of the three seats in Chhattisgarh and Udhampur in Jammu and Kashmir.
By 10 a.m., long queues of men and women were seen outside most polling centres.
A total of 1,767 candidates are in the fray in Bihar, Chhattisgarh, Jammu and Kashmir, Jharkhand, Karnataka, Madhya Pradesh, Maharashtra, Manipur, Odisha, Rajasthan, Uttar Pradesh and West Bengal.
Simultaneous balloting is being held for 77 of the 147 assembly seats in Odisha and two assembly constituencies in West Bengal. The earlier polling in Odisha took place April 10.
Election has already taken place in 111 Lok Sabha constituencies in the earlier five rounds of balloting that began April 7. Thursday will see the largest number of Lok Sabha seats in contention until now.
The Bharatiya Janata Party (BJP) claimed it was confident of winning most of the seats in Thursday's battle.

Former central minister Ananth Kumar voiced confidence about the BJP's ability to do well in Karnataka, where it is the main opposition party to the ruling Congress.
Central minister Jyotiraditya Scindia brushed aside the BJP's allegations. "There is no Modi wave," he said after voting in Guna in Madhya Pradesh, referring to the BJP's prime ministerial candidate Narendra Modi.
