"I doubt whether free and fair polls is possible in Bengal with a section of officials working either under pressure or on behalf of the ruling Trinamool Congress," said Mitra.
Questioned about the functioning of the state Chief Electoral Officer (CEO) Sunil Gupta, Mitra said the department was a non-performing one.
"The CEO's office has been non-performing. I don't know whether the office knows how to work or doesn't want to work," said Mitra.
Asked about the possibility of a post-poll alliance with the Trinamool Congress, Mitra said "Those who deny to acknowledge the existence of the Congress, will they be interested in forging an alliance with us? They will be in a better position to answer this. We are confident of UPA-3 coming to power.
