The State of Palestine (Arabic: دولة فلسطين Dawlat Filasṭin) is a sovereign state that was proclaimed on 15 November 1988 by the Palestine Liberation Organization's (PLO's) National Council (PNC) in exile in Algiers which unilaterally adopted the Palestinian Declaration of Independence. It claims the Palestinian territories (defined according to the 1967 borders) and has designated Jerusalem as its capital. The areas constituting the State of Palestine have been occupied by Israel since 1967. The 1974 Arab League summit designated the PLO as the "sole legitimate representative of the Palestinian people" and reaffirmed "their right to establish an independent state of urgency.The PLO held observer status at the United Nations as a "non-state entity" from 22 November 1974, which entitled it to speak in the UN General Assembly but not to vote. After the Declaration of Independence, the UN General Assembly officially "acknowledged" the proclamation and voted to use the designation "Palestine" instead of "Palestine Liberation Organization" when referring to the Palestinian permanent observer. In spite of this decision, the PLO did not participate at the UN in its capacity of the State of Palestine's government. On 29 November 2012 the UN General Assembly passed resolution 67/19 upgrade Palestine from an "observer entity" to a "non-member observer state" within the United Nations system, and implicitly recognizing PLO's sovereignty. In 1993, in the Oslo Accords, Israel acknowledged the PLO negotiating team as "representing the Palestinian people", in return for the PLO recognizing Israel's right to exist in peace, acceptance of UN Security Council resolutions 242 and 338, and its rejection of "violence and terrorism". As a result, in 1994 the PLO established the Palestinian National Authority(PNA or PA) territorial administration, that exercises some governmental functions in parts of the West Bank and the Gaza Strip. In 2007, the Hamas takeover of Gaza Strip politically and territorially divided the Palestinians, with Abbas's Fatah left largely ruling the West Bank and recognized internationally as the official Palestinian Authority, while Hamas has secured its control over the Gaza Strip. In April 2011, the Palestinian parties signed an agreement of reconciliation, but its implementation has stalled since. As of November 2012, 131 (67.9%) of the 193 member states of the United Nations have recognised the State of Palestine. Many of the countries that do not recognise the State of Palestine nevertheless recognise the PLO as the "representative of the Palestinian people". The PLO's executive committee is empowered by the PNC to perform the functions of government of the State of Palestine. The UN has permitted Palestine to title its representative office to the UN as 'The Permanent Observer Mission of the State of Palestine to the United Nations', and Palestine has instructed its diplomats to officially represent 'The State of Palestine', and no longer the 'Palestine National Authority.' On 17 December 2012, UN Chief of Protocol Yeocheol Yoon declared that 'the designation of "State of Palestine" shall be used by the Secretariat in all official United Nations documents', thus recognising the title 'State of Palestine' as the nation's official name for at least all UN purposes.
