TMC rebel Dipendu Biswas writes apology letter to Mamata, says `joining BJP was bad decision`

The West Bengal assembly elections were no less than a big battle for the state. We have seen many politicians jumping from Mamata Banerjee-led Trinamool Congress (TMC) to Bharatiya Janata Party (BJP). In one such incident, TMC leader Dipendu Biswas has written a letter to TMC supremo Mamata Banerjee seeking her forgiveness on Monday (May 31).
