There is no tactic arrangement between former ally Chirag Paswan and the BJP leadership, senior BJP leader Ravindra Kishore Sinha said, quelling speculation about his party silent approval to the Lok Janshakti Party chief splitting with the alliance and eating into key ally JD(U)'s vote share. He, however, refused comment when asked if the BJP would welcome him back in the National Democratic Alliance, if the need arises. "The problem is between Chirag Paswan and Nitish Kumar. We would have done much better had all constituents of the NDA been together," Mr Sinha said.
