“An emergency meeting of the Arab League in June 1988 gave the PLO financial control of support for the Palestinians, thereby virtually acknowledging Arafat as their spokesman. In response, Hussein renounced all Jordanian claims to the West Bank, allowing the PLO to assume full responsibility there. He dissolved the Jordanian parliament (half of whose members were West Bank representatives), ceased salary payments to 21,000 West Bank civil servants, and ordered that West Bank Palestinian passports be converted to two-year travel documents. When the Palestine National Council recognized the PLO as the sole legal representative of the Palestinian people and proclaimed the independence of a purely notional Palestine on November 15, 1988, Hussein immediately extended recognition to the Palestinian entity.”
