TMC MP Abhishek Banerjee on Tuesday said the "double-engine government" has failed in Tripura and TMC can give a bright future to the state. "If BJP is...virus, then TMC is its vaccine," Banerjee stated. "BJP's irresponsible...careless comments have created chaos and infighting within...country," he added. He was speaking at a rally in Tripura ahead of the Assembly bypolls.
