There are reports that the party chief's stance against the creation of Telangana has resulted in a rift in the party.
The leaders of the party, particularly from the Telangana region, have revolted against Chiranjeevi's decision to oppose the creation of the new state.
Chiranjeevi is believed to be holding another round of talks over the matter with his party MLAs.
Around 16 PRP MLAs hailing from the coastal and Rayalaseem regions of Andhra Pradesh had submitted their resignations last week protesting the division of the state to establish a separate Telangana.
Chiranjeevi himself comes from coastal Andhra and represents Tirupati assembly constituency.
