The unity agreement between Herzog and Hatuna party leader MK Tzipi Livni included rotation over the job of the opposition chief, but to this day Livni has not demanded the position.
Be that as it may, Hatnua officials believe Livni has no intention of giving up the job now. As far as she is concerned, the rotation agreement remains valid, and she expects it to be honored.
Theoretically, Avi Gabbay, who defeated Herzog in the battle for the Labor party's leadership, is meant to be bound by the agreement his predecessor reached with Livni, but he has been in no rush to declare that
The response from Gabbay's media advisor leaves matters wide open: "We're happy about Isaac Herzog's appointment. He still has a month in the role (of opposition head). We'll release further details at a later date."
The head of the opposition must be a sitting member of Knesset, which is why Gabbay, who was elected to lead Labor but never voted into the parliament, cannot take on the job himself.
Labor officials said Gabbay was likely to want to appoint MK Shelly Yachimovich for the top opposition job. This could prompt Livni to break off the partnership between her Hatnua party and the Labor party, citing a breach of the agreement with Herzog.
The opposition head is a state official. He receives security briefings from the prime minister, protection services from the Shin Bet and travels in a non-military armored car.
Herzog's spot in the Knesset will be filled by former MK Robert Tiviaev.
