The party rejected my suggestion and decline to understand the ground situation in Assam .And hence, it is not possible for me to remain in a party that does not value the Assamese sentiment”, said Pathak. He was a TMC MLA from 2011 to 2016,. Frankly,”The TMC has no existence in Assam,” he added. All parties in Assam are united on the foreigners’ issue, he added.
