Cooch Behar, April 5 -- Prime Minister Narendra Modi on Sunday attacked the ruling Trinamool Congress government in West Bengal and said it will be held to account for its "sins" after poll results on May 4 and assured that a BJP government will ensure development and drive away infiltrators.

Addressing an election rally here, PM Modi said the huge number of people here in Cooch Behar has made it clear that the "Trinamool Congress's time is up".

"No matter how much the TMC goons intimidate you on polling day, you must have trust in the law. In this election, fear will be driven out of Bengal. Confidence will awaken through the BJP's grand victory... I assure you, after this election, a full accounting of their (TMC's) sins will be done....
