Labor Party Chairman Amir Peretz announced his resignation from his position as head of the Histadrut at a Sunday morning press conference.
Peretz said that he would officially leave the position in the beginning of January.
The announcement was expected, as was his endorsement of Ofer Ayani as his successor in the position.
Peretz's support does not pave a sure way for Ayani, whose appointment needs an okay from the Workers' Council.
During the press conference, Peretz said that when he began his term as Histadrut chairman, the veteran labor organization was at the brink of collapse, and that he had led the organization to a renewed status in Israeli society.
