"I should finally like to say that, besides working towards peace in the Middle East, which the European Union must continue to strive for, I am just as keen to seeing Europe play a much more active part in ensuring that the referendum on self-determination in the Western Sahara, which is under serious threat, is held in the conditions stipulated under UN authority."
Enfin, je voudrais dire qu' outre la paix au Moyen-Orient, pour laquelle l' Union européenne doit continuer à uvrer, je souhaite aussi ardemment que l' Europe joue un rôle beaucoup plus actif afin que le référendum d' autodétermination au Sahara occidental, gravement menacé, ait lieu dans les conditions fixées, sous l' autorité de l' ONU.
