Mamata Banerjee's six ministers could have sent their resignation letters to the Prime Minister. But they chose to hand deliver them this evening, before setting out to meet the President and formally end the Trinamool Congress's partnership with the Congress-led UPA government. At the time that her ministers were at the PM's residence, Mamata Banerjee made a speech at an event in Gaighata, West Bengal, to show that for her, it was business as usual. Video courtesy: NDTV
