The highest turnout in the 8th phase was 81.28 per cent in the six seats in West Bengal, which Trinamool Congress is trying to wrest from Left Front, followed by 76 per cent in Seemandhra, where voters chose 25 representatives to Lok Sabha and 175 members of the proposed assembly simultaneously.

The talking point today was Amethi in Uttar Pradesh, where Rahul Gandhi is contesting for the third time in a row, as a 55.2 per cent polling was recorded.

Modi had made an aggressive campaign in Amethi, the bastion of Gandhi family for more than three decades, on the last day of electioneering for the 8th phase on April 5.
