Raipur, June 01: In an attempt to bring a change in government in Chhattisgarh in the ensuing assembly polls in the state, the BJP today launched three `parivartan rallies' simultaneously. While BJP national president led the rally from Ratanpur in Bilaspur district, Jharkhand Chief Minister Arjun Munda and Union Tribal Affairs Minister Juel Oram led the rallies from Dantewada and Dongargarh in the state respectively. Earlier, speaking to reporters, Naidu claimed that these rallies would bring change of government in the state since Ajit Jogi government has been "involved in large scale corruption". Union Minister of State for Forest and Environment Dilip Singh Judeo and BJP national vice-president Karuna Shukla would be in-charge of Ratanpur while state BJP chief Dr Raman Singh and leader of opposition Nand Kumar Sai will lead the rally at Dantewada with Union Minister for Mines Ramesh Bais given charge of Dongargarh, party sources said. The three rallies would pass through various places for 18 days and carry out about 300 meetings, sources added. Bureau Report
