The Trinamool Congress hit out at the Centre on Sunday, alleging political vendetta as the CBI served a notice to party MP Abhishek Banerjee's wife, asking her to join the probe in the coal pilferage case. In a statement, the party said that people will give a befitting reply to the BJP over this during the polls. The statement said all BJP allies have left so the only loyal allies are CBI and ED. Trinamool Congress spokesperson and MP Sougata Roy alleged the CBI visiting Abhishek's house was nothing but political vendetta.
