Bihar chief minister Nitish Kumar’s Janata Dal (United) on Sunday made it clear that it will not join the Union council of ministers again, but rebuffed speculations of a rift with ally BJP asserting “all is well”. JD(U) national president Rajiv Ranjan Singh alias Lalan, who addressed a press conference here, however, dismissed queries about Kumar’s absence at the NITI Aayog meeting chaired by Prime Minister Narendra Modi, with the terse remark “you should ask the chief minister”.
