"Not worth taking note" was Bihar Chief Minister Nitish Kumar’s reply on queries about "disgruntled" key aide Upendra Kushwaha's claim of "big leaders" in the JD(U) maintaining "deep" contacts with those in the BJP. Kushwaha, the parliamentary board chief of the JD(U), had made the claim on Sunday, exasperated by the controversy surrounding his meeting with BJP leaders last week in Delhi.
