The President shall invite the President of the Commission, the Commissioner responsible for relations with the European Parliament or, by agreement, another Commissioner, to make a statement to Parliament, after each meeting of the Commission, explaining the main decisions taken, unless, for timetabling reasons or because of the relative political relevance of the subject- matter, the Conference of Presidents decides that this is not necessary. The statement shall be followed by a debate of at least 30 minutes in which Members may put brief and concise questions.
