Kolkata: Bollywood actor Mithun Chakraborty on Sunday joined the Bharatiya Janata Party (BJP) in a rally at Kolkata.

Mithun Da was welcomed by the BJP's National General Secretary Kailash Vijayvargi and other state leaders. Former Trinamool Congress leader and former Union Minister Dinesh Trivedi, who had joined the BJP was also present.

Prime Minister Narendra Modi is expected to arrive at the ground at 1.45 p.m. aboard a chopper from the Netaji Subhas Chandra Bose International (NSCBI) airport.

Kolkata has been virtually covered with a tight security blanket by the city police and security agencies coming from the Centre.

The rally in the presence of Prime Minister Narendra Modi will mark the culmination of the BJP's state-wide Parivartan Yatra that covered Bengal's 294-assembly constituencies. Security agencies put up four-layered barricades in front of the podium from where PM Modi is slated to address crowds.

The 294-member West Bengal Assembly will go to the polls in eight phases between March 27 and April 29. The counting will take place on May 2.
