Addressing a rally in West Bengal, PM Narendra Modi on Friday said he has a special relationship of "chai" (tea) with North Bengal. "You grow tea, I make tea...And it makes me wonder...Why Didi (WB CM Mamata Banerjee) is not fond of chaiwallahs," he added. "WB government has defamed "maati" (soil) and has made "maanush" (people) helpless," he further said.
