 After the first round of voting put Peres in a commanding lead, but just short of the absolute majority required for election, Rivlin and Avital bowed out and Peres was elected easily in the second round.
An election for President of Israel was held in the Knesset on 28 October 1957 following the end of Yitzhak Ben-Zvi's five-year term in office.
