Meghalaya Congress MLAs, including former CM Mukul Sangma, are all set to join Trinamool Congress. Mukul Sangma was unhappy with the appointment of Shillong MP Vincent H Pala as the party's state president. He recently met with TMC strategist Prashant Kishor, general secretary Abhishek Banerjee and TMC Rajya Sabha member Sushmita Dev.
