Congress chief Sonia Gandhi will take a final call on the induction of election strategist Prashant Kishor in the party after a series of meetings with senior leaders, many of whom are opposed to the idea, sources told NDTV on Wednesday. Mr Kishor, who had a botched stint with Nitish Kumar's Janata Dal (United), had a series of meetings with the three Gandhis in July, where a role for him in the party was explored in detail.
