Former Minister Michael Harish has been chosen to be the temporary chairman of the Labor Party, whose chairman Ehud Barak abandoned it last week.
Faction members have not yet decided on a date for the primary elections of the party, stating that all decisions will be made in the coming meetings.
Harish is to be officially instated at the Knesset Monday.
"It has been decided that Harish is most suited at this time to take upon himself the duty of running and organizing the party, as well as resurrecting its operations," a statement from the party said.
Saturday revealed a conflict between members of the Labor faction who consider themselves worthy of leading the party regarding the date on which primary elections should be held.
MK Isaac Herzog, who enjoys widespread support from voters, is interested in holding the vote within the next 2-3 months, but Avishai Braverman and Amir Peretz were unconvinced, saying more members should be sworn in first.
