Poll strategist-turned-politician Prashant Kishor on Tuesday took a sharp jibe at Jyotiraditya Scindia over his resignation from the Congress, attributing his political success to his family name. Mr Kishor said Mr Scindia has made "little" contribution as "mass leader, political organiser or administrator". Mr Scindia comes from the erstwhile Gwalior royal family. Several members of his extended family have been in politics.
