Former Union Minister Babul Supriyo on Tuesday formally submitted his resignation as a BJP MP from the House to the Lok Sabha Speaker Om Birla.

After his meeting with the LS speaker, Supriyo said, "My heart is heavy as I had begun my political career through BJP. I thank the Prime Minister (Narendra Modi), party chief (JP Nadda) and (Union Home Minister) Amit Shah. Confidence was shown in me. I'd left politics wholeheartedly. I thought that if I'm not a part of the party, I shouldn't keep the seat for myself."
