West Bengal state Congress president and leader of the Congress party in the Lok Sabha Adhir Ranjan Chowdhury led a rally in Kolkata on Friday to take on the ruling Trinamool Congress in the state and the BJP which is going all guns blazing in Bengal. Mr Chowdhury told NDTV in the battle between the Trinamool Congress and the BJP, the Left and the Congress may have suffered but it was a wrong perception that this electoral battle was only between the BJP and the Trinamool. He said the alliance between the Left and the Congress was a force to reckon with and seat sharing talks between them are moving smoothly.
