Leadership failure is the main reason behind YSRCP legislators leaving the party, Jaggampeta MLA Jyothula Nehru, who recently quit the party recently to join TDP, has said. Speaking to press persons at Tirumala after offering prayers at Lord Venkateswara temple here on Sunday, Nehru came down heavily on YSRCP chief Jaganmohan Reddy. “He (Jagan) is of no use even as Opposition leader. He does not have any political maturity needed for a political leader," he said and added that it was those 'handicaps' of Jagan that had prompted him to crossover to TDP. He said he had quit the party only after coming to conclusion that there would be no change whatsoever in attitude of party top leadership.
