The CBI has summoned former Bihar Chief Minister and RJD chief Lalu Yadav for questioning in the land-for-jobs case, a day after his wife Rabri Devi was grilled at her residence in the case. The CBI summons came after several Opposition leaders, including their son and Bihar minister Tejashwi Yadav, wrote a joint letter to Prime Minister Narendra Modi over the alleged misuse of central agencies. However, the CBI says it was a pre-decided appointment.
