text: For example , the President may be an MEP , or more significantly the Commission President ( who already sits in the European Council ) . This would allow the European Council to concurrently appoint one person to the roles and powers of both President of the European Council and President of the European Commission , thus creating a single presidential position for the Union as a whole .
simplified: The Union has several other presidents , such as the president of the European Parliament and the president of the European Commission .
