Trinamool Congress leader Derek O'Brien was suspended from parliament today for the rest of the Winter Session after he allegedly threw the rule book at the Chair and walked out of the Rajya Sabha during protests over an election reforms bill. But Mr O'Brien, reacting to the allegation, snapped: "Oh! Really? Who said I threw the rule book? Show me the footage." He went on to demonstrate, with a bottle, what the act of "throwing" is.
