Congress leader Mani Shankar Aiyar said West Bengal CM Mamata Banerjee is the leader of I.N.D.I.A bloc. "I hope that instead of trying to remain in this position, which belongs to smaller parties -be it MK Stalin, Mamata, Akhilesh Yadav, Tejashwi Yadav, or someone else - Rahul Gandhi should let them handle it," he stated.
