Congress and TMC are partners in UPA at centre and have coalition government in West Bengal. The relationship between the two has worsened in recent days. There is talk of Congress aligning with SP after UP elections.
There are no permanent friends or permanent enemies in politics. Congress needs TMC at centre. TMC does not need Congress in West Bengal. Both call each other CPI-M’s B team and compare to watermelon, green outside, red inside.
Mamata Banerjee, leader of TMC, opposed Congress on Teesta River Water Treaty, petrol price hike, FDI in retail. TMC voted for Lokpal Bill in Lok Sabha and opposed it in Rajya Sabha and moved amendments. Dinesh Trivedi said he had opposed Lokpal Bill in cabinet. He was overruled.
