Meanwhile, expressing pleasure over the poll results in the states of West Bengal and Assam, Home Minister P Chidamabaram on Friday described victory of TMC-Congress alliance in West Bengal and Congress in Assam as "spectacular".

In a statement, Chidambaram said he was delighted by the massive victory recorded by the TMC-Congress alliance in West Bengal and the Congress party in Assam.

"In both states our alliance pledged to work for inclusive growth, providing security to all the people, and working for peace and harmony. The scale of the victory in both states is truly spectacular. I spoke to Mamata Banerjee and Tarun Gogoi earlier today and offered them my warmest congratulations," he said.
