After thumping victory in recently held state elections seems given a lot of confidence to the leader of TMC and now she is planning to occupy the center stage in national politics, sources say. Ms Mamta Didi on “Sthapana Diwas” of the party delivered a lecture in Hindi and English like a national stateswoman and deliberated on all burning problems being faced by country and countrymen, her speech was live shown on large screens in almost big cities including in constitutional club, Delhi, where almost all big leaders of all parties invited by TMC attended, sources say.  Sharad Pawar with his daughter is the person working on the agenda to bring all big and small parties under one umbrella to challenge BJP in the next parliamentary elections. In the constitutional club, representatives of Akali Dal and Telangana Rashtra Samiti were also present, sources say. These parties were earlier supporters of the BJP even Shiv Sena was also represented by Ms Priyanka Chaturvedi. Sources say this is an indication that BJP is losing grip on their erstwhile supporters. Ms Mamta Didi is expected in the capital next month and surely she will meet all political leaders of all other parties san BJP, sources say. Meeting with leaders will pave the way for opposition unity and probably a common platform will be formed to fight next elections together?
