Three lakh people are expected to take part in the Kanpur rally, Maithani said.
Kanpur BJP wanted to hold the rally in a railway field in Nirala Nagar, but Railways refused to accede to the request, Maithani said.
The arrangement for a venue of the rally still needs to be made, he said. Other options for the venue include the Moti Jheel field and Brajendra Swaroop Park, he said.
According to BJP Kanpur Zone incharge, Bal Chand Mishra, BJP will win all six seats of Kanpur if Modi starts his election campaign from here, as people will come from far to listen to him speak.
