Shiv Sena (UBT) leader Aaditya Thackeray on Wednesday said that the West Bengal Chief Minister Mamata Banerjee was "fighting like a tigress", and her fight was important for her state, reported the PTI.

In a setback to the Opposition`s INDIA bloc, Mamata Banerjee earlier in the day announced that the Trinamool Congress (TMC) would go it alone in her state in the coming Lok Sabha elections.
