beginning, the PLO was designed as a government in exile, with a parliament, the Palestine National Council (PNC), chosen by the Palestinian people, as the highest authority in the PLO, and an executive government (EC), elected by the PNC. In practice, however, the organization was rather a hierarchic one with a military-like character, needed for its function as a liberation organization, the "liberation of Palestine". The Palestinian National Charter describes the ideology of the PLO. A constitution, named "Fundamental Law", was adopted, which dictates the inner structure of the organization and the representation of the Palestinian people. A draft Constitution was written in 1963, to rule the PLO until free general elections among all the Palestinians in all the countries in which they resided could be held. The Constitution was revised in 1968. Institutions The Palestinian National Council has 740 members and the Executive Committee or ExCo has 18 members. The Palestinian Central Council or CC or PCC, established by the PNC in 1973, is the second leading body of the PLO. The CC consists of 124 members from the PLO Executive Committee, PNC, PLC and other Palestinian organizations. The EC includes 15 representatives of the PLC.

The CC is elected by the PNC and chaired by the PNC speaker. The PNC serves as the parliament for all Palestinians inside and outside of the Occupied Palestinian Territory, including Jerusalem. The PLO is governed internally by its "Fundamental Law", which describes the powers and the relations between the organs of the PLO. Ahmad Shukeiri was the first Chairman of the PLO Executive Committee from 1964 to 1967. In 1967, he was replaced by Yahia Hammuda. Yasser Arafat occupied the position from 1969 until his death in 2004. He was succeeded by Mahmoud Abbas (also known as Abu Mazen). According to an internal PLO document, the current PNC continues to act if elections are not possible. In absence of elections, most of the members of the PNC are appointed by the executive committee. The document further states that "the PNC represents all sectors of the Palestinian community worldwide, including numerous organizations of the resistance movement, political parties, popular organizations and independent personalities and figures from all sectors of
