The RLM President Upendra Kushwaha on Sunday urged Bihar CM Nitish Kumar to take a firm decision in a ‘timely manner’, cautioning that any delay in this would lead to 'irreparable' damage to his party – the JD(U). Kushwaha, a long-term friend of Nitish, said this while greeting his son Nishant on the latter’s birthday and also described him as the ‘new hope of JD(U)’.
