In Varanasi, Aam Aadmi Party's Kejriwal, a former Delhi chief minister, claimed he was sure to defeat Modi. "The situation has changed in the last three days, and now everyone is saying Modi is losing."
Kejriwal insisted that the Varanasi battle was no more a triangular contest. "(Congress candidate) Ajai Rai does not feature anywhere. I feel it is a direct fight with Modi."
The BJP is equally confident of ensuring Modi's win by a huge margin in Varanasi, the second Lok Sabha seat from where the Gujarat chief minister is contesting besides Vadodara in his home state.
Modi Monday urged the electorate to vote in large numbers. His appeal, telecast by television news channels, triggered an immediate protest from the AAP which called it a violation of the model code of conduct.
Ajay Rai courted controversy when he walked into a polling station with the party symbol tucked on his kurta -- a violation of electoral laws.
Officials reported brisk polling in the other 17 constituencies of Uttar Pradesh too, including Azamgarh where Samajwadi Party chief Mulayam Singh Yadav is considered the front-runner.
