The Zionist Union party officially broke up Wednesday, splitting into its two constituent parties, Labor and Hatenua.
This Knesset approved the Zionist Union's request to divide. After the move, the Labor party will have 18 MKs and Hatenua 6.
The request was submitted only a day after Avi Gabbay shocked Zionist Union members when he announced he was ending Labor's partnership with Hatenua leader Tzipi Livni.
"It is good that the doubts have been dispelled and we can focus on the important national challenges we face," Livni wrote on Twitter.
