Security was beefed up for Bharatiya Janata Party's (BJP) prime ministerial candidate Narendra Modi's "Vijay Shankhnaad" rally on Thursday.
While metal detectors were installed at the entrance gates, parking slots were earmarked several kilometres away from the venue.
"After the Patna bomb blasts (October 27), the district administration is not taking any chance and has beefed up security apparatus," an official told IANS.
"Watch towers, special slot for OB vans, a guarded press box, a huge stage and the ground decked up with hoardings and flags are in place. More than a lakh people should turn up," activist Shravan Kumar Singh said.
State party leaders, including former chief minister Kalyan Singh, are already camping in Agra.
For Uttar Pradesh, Thursday promises to be full of fireworks with three rallies. While the Samajwadi Party (SP) will hold its rally in Bareilly, the Congress will be seen in action in Lucknow and the BJP in Agra.
