Prime Minister of Israel Basic Laws of Israel explicitly vest executive power in the government, of which the Prime Minister is the leader. The office of Prime Minister came into existence on 14 May 1948, the date of the Declaration of the Establishment of the State of Israel, when the provisional government was created. David Ben-Gurion, leader of Mapai and head of the Jewish Agency became Israel's first Prime Minister. The position became permanent on 8 March 1949, when the first government was formed. Ben-Gurion retained his role until late 1953, when he resigned in order to settle in the Kibbutz of Sde Boker.
Prime Minister of Israel prevents one party from winning the 61 seats needed for a majority. In 1996, when the first such election took place, the outcome was a surprise win for Benjamin Netanyahu after election polls predicted that Peres was the winner. However, in the Knesset election held at the same time, Labour won more votes than any other party (27%). Thus Netanyahu, despite his theoretical position of power, needed the support of the religious parties to form a viable government. Ultimately Netanyahu failed to hold the government together, and early elections for both prime minister and the Knesset were called in 1999.
