Trinamool Congress

The All India Trinamool Congress (Bengali: সর্বভারতীয় তৃণমূল কংগ্রেস; Hindi: सर्वभारतीय तृणमूल कांग्रेस; abbreviated AITMC, TMC or Trinamool Congress) is a sub-national state-level ("state party") ruling political party in West Bengal. Founded on 1 January 1998 as a breakaway faction of the Indian National Congress, the party is led by its founder and current Chief Minister of West Bengal Mamata Banerjee. Prior to the 2014 General Election it was the sixth largest party in the Lok Sabha with 19 seats; following that election, it is currently the fourth largest party in the Lok Sabha with 34 seats.

On 18 September 2012, TMC Chief, Mamata Banerjee, announced her decision to withdraw support to the UPA after the TMC's demands to undo government-instituted changes including FDI in retail, increase in the price of diesel and limiting the number of subsidised cooking gas cylinders for households, were not met
