Janata Dal (United) leader Sharad Yadav has become persona non grata for the Bihar Chief Minister Nitish Kumar-led party. However, he cannot gather the courage to expel Yadav, hoping that his one-time mentor would quit on his own. This, despite the suspension of several other rebel leaders on Monday. Party spokesperson K C Tyagi, who also counts Yadav as a mentor, said on Monday that Sharad Yadav should now be called Sharad Tyagi. Translates into English, “tyagi” means the renouncer.
