المهدي بن بركة
After the events of March 23, suspected dissidents including communists and Iraqi teachers were arrested. In April, Hassan II tried to reconcile with the opposition, receiving at Ifrane a delegation from the "Union nationale des forces populaires", which included, notably, Abderrahim Bouabid, Abdelhamid Zemmouri and Abderrahmane Youssoufi. They proposed to form a government and demanded to transmit their message to Mehdi Ben Barka. But these discussions resulted in no concrete action.
