The Yesh Atid party is expected to set up a committee to elect the party leader for the first time since the faction was established in 2012.
The party will publish new bylaws tomorrow that will announce the plan.
Some 1,000 party members will convene to elect a chairman in January, according to Hebrew media reports.
Foreign Minister Yair Lapid is expected to win the election and is automatically a candidate. Lapid has led Yesh Atid since he founded the party and is set to become prime minister in 2023.
Other candidates can enter the running until December 21.
The party’s electoral slate in future votes will not be up for election, however.
