“The number of seats is not important, but defeat of the saffron party is the main agenda,” he said.
Choudhury said his party is also in talks with Tipra Motha chairman Pradyot Debbarma.
The announcement marks a tectonic shift in the state’s political landscape, as the Congress was the main opposition to the CPI(M)-led Left Front, which ruled Tripura for 25 years before being routed by the BJP in 2018.
The ruling BJP, meanwhile, said that an alliance between the CPI(M) and the Congress would augur well for it.
“Earlier, they used to maintain cozy relations covertly, and now it will be in the open. In fact, the CPI(M) had ruled for so long because of its understanding with the Congress,” BJP state president Rajib Bhattacharjee said.
