At a function in Howrah district, the 48-year-old actress-singer was formally inducted into the party fold in the presence of senior BJP leader and Union Finance Minister Arun Jaitley.
BJP's state leadership has been trying hard to attract film and television artistes from the state. They already have singer-turned-MP Babul Supriyo and Bengali film actor George Baker among others.
Besides 'Mahabharat', Ganguly is a well-known face on the television due to her roles in serials like 'Karam Apnaa Apnaa' and 'Agle Janam Mohe Bitiya Hi Kijo'.
