Top scientist Avinash Chander, who was recently ousted as chief of the Defence Research and Development Organisation or DRDO has said the termination of his contract was "totally unexpected" and that he was taken by "surprise" by the swift move of the government. "Sacking is not a good word to hear after 42 years of service," Mr Chander told NDTV, also saying that Defence Minister Manohar Parrikar was well within his rights to choose his team. The minister had said the government wanted younger scientists on the team.
