Mubarak was elected chairman of the Organization of African Unity in 1989, and again at the OAU summit in Cairo in June 1993. Domestically, since 1991, Mubarak has undertaken an ambitious reform program to reduce the size of the public sector and expand the role of the private sector. There has also been a democratic opening and increased participation in the political process by opposition groups. The November 1990 National Assembly elections saw 61 members of the opposition win seats in the 454-seat assembly, despite a boycott by several opposition parties citing possible manipulation by Mubarak's National Democratic Party (NDP). The opposition parties have been weak and divided and are not yet credible alternatives to the NDP. Freedom of the press has increased greatly. While concern remains that economic problems could promote increasing dissatisfaction with the government, President Mubarak enjoys broad support. For several years, domestic political debate in Egypt has been concerned with the phenomenon of "Political Islam," a movement which seeks to establish a state and society governed strictly by Islamic doctrine. The Muslim Brotherhood, founded in Egypt in 1928, is legally proscribed but operates more or less openly. Egyptian law, however, prohibits the formation of religion-based political parties. Members of the Brotherhood have been elected to the People's Assembly as independents and have been elected to local councils as candidates on the Socialist Labor Party ticket.
