Senior BJP leader Arun Shourie's comments against BJP and its leadership were an act of "gross indiscipline",senior party leader Ram Naik has said. "What Shourie has done is gross indiscipline," Naik,who heads BJP's disciplinary panel,said in Mumbai on Tuesday. Asked what action would be taken against Shourie,the former Union minister said,"it is for the party's parliamentary board to decide". Naik,however,declined to comment on expelled BJP leader Jaswant Singh,saying "it is a closed chapter." Shourie,the 68-year-old journalist-turned-politician,has hit out at BJP president Rajnath Singh calling him an "Alice in Blunderland" and the party as a 'kati patang' (kite without a string).
