Ever since the once most trusted lieutenant of Mamata Banerjee has joined the BJP, he has become a full scale Delhiite. Not only has he ditched his city of origin Kolkata, he has in fact deleted his name from the city’s voters’ list and has enrolled himself as a voter in Delhi. Sources say that he is likely to file a high-priced defamation case in Delhi, which is possible only if he is a Delhi voter.
