The AIFB's decision comes in the midst of reports that a large section of state Congress leaders are favourable to an alliance with the CPI(M)-led Left Front in order to oust the ruling TMC from power.
"We feel both BJP and Congress are capitalist forces. We should maintain a equi-distance from both these parties. Our party's stand is clear. We are not in favour of aligning with the Congress in order to take on the TMC in West Bengal. The Left will alone take on the ruling party," AIFB general secretary Debabrata Biswas told PTI.
"The Left Front is not a regional force. If there is an alliance with the Congress in Bengal, what will happen in Kerala and Tripura where Congress is our main opposition?" Biswas wanted to know.
Asked if the AIFB would walk out of the Left Front in the event of the CPI(M) going in for the alliance, Biswas said, "This is a hypothetical question. It can't be answered this way."
CPI(M) general secretary Sitaram Yechury earlier this month had said, "The question will come in January. We will tell you. Right now we are involved in struggles and party's organisational activities and our upcoming Plenum session.
