When he sings, they say, it is from his heart. When Babul Supriyo is upset, he pours his heart out. That’s precisely what he did when he was removed from the Union ministry in the latest reshuffle a couple of months ago. Following his removal, he announced quitting politics and decided to resign from the Lok Sabha. But BJP national president J.P. Nadda prevailed and Supriyo, who joined politics ahead of the 2014 general elections and served as a junior Union minister, decided not to resign. He stayed put. Yet, speculation swirled that his association with the BJP won’t be long. Questions were asked: Where would he go next? He answered that this weekend. The playback singer/politician joined Mamata Banerjee’s Trinamool Congress.
