Election strategist-turned-politician Prashant Kishor's lunch meeting today with Shiv Sena chief Uddhav Thackeray and his son Aditya Thackeray has caused much buzz in election season. Aditya Thackeray described him as "special visitor" in a tweet that showed the Thackeray duo chatting with Prashant Kishor, who joined politics last year as the number two man of Bihar's ruling Janata Dal United.
