In a major setback for the Rashtriya Janata Dal (RJD), the CBI has filed a chargesheet against Bihar Deputy Chief Minister Tejashwi Yadav and his parents and former chief ministers Lalu Yadav and Rabri Devi in the land-for-jobs scam. Tejashwi and Lalu Yadav have been at the forefront of efforts to unite the opposition and played a key role in organising the mega meet of 16 opposition parties that was held in Patna on June 23.
