Days after the Central Bureau of Investigation (CBI) reopened a corruption case against Rashtriya Janata Dal (RJD) Chief Lalu Yadav, Bihar Chief Minister Nitish Kumar took a veiled dig at the BJP-ruled central government. Nitish Kumar, who parted ways with the BJP earlier this year and tied up with the RJD, today alleged that the corruption case was reopened because his party has formed government in Bihar with Mr Yadav's party.
