The city's famed Brigade Parade Ground is preparing for a massive public rally to be addressed by Prime Minister Narendra Modi today. This is his first visit to West Bengal since the state's Assembly poll dates were announced last week, although he has already been here at least three times in the past few months. What could add glitz to the event is the possibility of popular actor Mithun Chakraborty joining in. Having been noncommittal when first asked about it yesterday, the party's state in-charge Kailash Vijayavargiya later in the day met up with the star at his residence in the capital's Belgachia locality.
