Union minister Rajiv Pratap Rudy today accused Bihar Chief Minister Nitish Kumar and RJD chief Lalu Prasad of indulging in politics of caste and appeasement, which he said, is the antithesis of the BJP's political philosophy. His remarks came amid speculation about the increasing bonhomie between JDU chief and Prime Minister Narendra Modi. He was speaking at a press conference in Bhopal.<br/><br/>The JD(U) had broken its 17-year alliance with the BJP in 2013 after Mr Modi was declared the BJP's prime ministerial candidate. Mr Kumar had last week called on Prime Minister, a day after he gave a miss to the luncheon meeting hosted by Congress president Sonia Gandhi for opposition leaders in Delhi. However, he had denied speculation, saying he met the prime minister to discuss Bihar-related issues.
