ALAPPUZHA: Addressing the general body meeting of the Sree Narayana Trust on Saturday, general secretary Vellapally Natesan said graft charges levelled against him by former SNDP yogam assistant secretary Kilimanoor Chandrababu was baseless. “I will stop public service activities, if Chandrababu proves the charge raised against me. Chandrababu said I had swindled `500 crore from the trust. The annual budget of the trust has never reached that figure at any given time. It has been as low as 10 pc of the alleged amount, he said.
