Indicating a political spat over the seat-sharing issue within the Opposition INDIA bloc, West Bengal Congress chief Adhir Ranjan Chowdhury has hit out at CM Mamata Banerjee, asserting that she was "busy serving" Prime Minister Narendra Modi. Moreover, Cowdhury also maintained that the grand old party did not want to establish an alliance with the TMC and could contest elections on its own in the general election.
