The paper aims to define the notion of comment as a communicative act not requested by the previous turn. In our corpus of political debates, comments convey a negative evaluation of the opponent and are generally addressed to the audience. Comments can be conveyed both through speech and body, through body posture, gestures or facial expression (body comments). In the present qualitative study we focused on facial and head comments, our aim being to single out the possible goals of the commenter when expressing negative evaluations of his opponent.
