Deputy Speaker Dawn Primarolo ordered Labour MP Ian Austin to "stand up", and then told him to "say sorry" after he referred to a Conservative MP as an "idiot".
The incident came during the last day of the Queen's Speech debate in the House of Commons, and came as shadow chancellor tried to deliver a speech.
