Yadav and the Special Election Observer visited a number of booths to ensure free and fair polls.
An official said on complaint of BJP, an AAP worker was detained in Shivpuri area. Speaking to reporters, Kejriwal declared that his is a direct fight with Modi and said Congress' Rai is not a challenger.
Rai, however, dismissed these claims and said the voters of Varanasi will elect him as he is the only “son of the soil” in the contest.
“How is it a triangular contest? Ajay Rai is nowhere. It is a direct contest with Narendra Modi ji. The situation has been changing in the last three days. Everyone is saying Narendra Modi ji will lose,” Kejriwal said.
Kejriwal left Varanasi later in the evening and said he would be back after two days.
