Trinamool Congress supremo and West Bengal Chief Minister Mamata Banerjee on Friday appealed to all non-BJP parties to come together to form a front and said she would be happy to attend deliberations on the issue.Speaking to media persons here, Banerjee said she is now fighting the battle against the BJP-led central government alone."I am now fighting this battle alone. I am requesting and appealing to all my friends from other political parties to come, sit together and form a front, maybe Federal Front or whatever name you give."But let us fight together. If anybody comes, I will be very happy. If they call me, I will be very happy to attend," she said.Banerjee has for long been harping on a federal front of non-Congress and non-BJP parties.With elections in five states approaching, Banerjee has been upping the ante and trying to project herself as the fulcrum of the anti-BJP political space.
