I believe the mother tongue of Parmanda Jha (So called vc of new Nepal) is maithali or bhojpuri. But he too this oath  in Hindi. Ok protest are going on as always nothing new about that but I wonder what if he had taken the oath in Maithali or Bhojpuri instead of Hindi would people not protest? What do you say.. And hey I am not bhojpuri or maithali supporter I speak nepali and that’s the only one I know.
