TEL AVIV—Israel’s Prime Minister Benjamin Netanyahu said on Monday he failed to form Israel’s next government after a September election that saw no clear winner, giving rival Benny Gantz the opportunity to create a coalition that would end the tenure of the country’s longest-serving premier.
President Reuven Rivlin said he would begin consultations Tuesday with the parties in the Knesset to initiate Mr. Gantz’s 28-day turn at trying to form a majority government of at least 61 seats in Israel’s parliament.
