PATNA, Aug. 10 -- Leader of the Opposition Tejashwi Prasad Yadav on Saturday flayed Union home minister Amit Shah for not making any statement regarding state's progress, unemployment, migration and poverty during his speech in Sitamarhi on Friday and accused the BJP leaders of indulging in negative politics. "People of Bihar would give nothing to Union home minister Amit Shah this time. He can make as many visits and stay in the state for as long he wants. They have nothing else to say except abusing RJD chief Lalu Prasad and me. They do not talk about state's progress or unemployment, migration and poverty," said Yadav, on returning from New Delhi. The Opposition leader also took oblique potshots at former Mokama MLA and strongman Anant Singh over his reported meeting with chief minister Nitish Kumar on Saturday. "I have nothing to say about them. They understand the language of guns. It is strange, an AK-47 is recovered from their house and later, the government helps them to get free. We do not get involved in such politics. People of Bihar know who is what," Yadav said, alluding to the charges against Singh of illegally having possession of AK-47 rifles and ammunition at his house in his native village a few years back....
