Poll strategist-turned-politician Prashant Kishor today aimed a series of questions at his former mentor Nitish Kumar, who expelled him from the Janata Dal United last month after an acrimonious war of words. Prashant Kishore questioned what he called Nitish Kumar's ideological compromise to stay in the alliance with the BJP. "Nitish-ji does not need to stay in the NDA coalition," Mr Kishor said.
