Also various negotiations between the UEDP-medhin opposition party and the AEUP opposition party failed. And this was a major problem for the AEUP that was originally united with UEDP-Medhin to make up the CUD because without UEDP-Medhin, CUD support in Addis Ababa would have been "no more than marginal." Most people, including UEDP-Medhin and Rainbow party, have pointed out the hardliners inside AEUP, particularly Hailu Shawel, were the reasons for the disagreements. Some members said AEUP leaders like Hailu Shawel "are chauvinists and dictators who think that they are the only best opposition party."
