SP chief spokesman Rajendra Chowdhury said the programme of the rallies has been finalised.
"Between April 7 to May 16, both leaders will address 11 joint rallies and RLD chief Ajit Singh will also be sharing stage with them," he said.
The first joint rally of SP-BSP-RLD will be held in Deoband (Saharanpur) on April 7, followed by rallies in Badaun, Agra, Mainpuri, Rampur, Firozabad, Kannauj, Faizabad, Azamgarh, Gorakhpur and Varanasi.
