Israeli politics never ceases to amaze! A union of Labour and Livni’s HaTnua has been widely anticipated, and several polls now have shown this combined list would win more seats than Likud. But a rotation of the premiership if the combined list is in a position to form a government? I never imagined such a deal.
As the article in Times of Israel notes, “There is a precedent for prime ministerial rotation in Israel. Labor’s Shimon Peres and Likud’s Yitzhak Shamir led the country in that format between 1984 and 1988.” But note the difference: that was two parties–still the two big ones back then–agreeing to take turns. This deal is that one party (or, here, alliance) will swap the leader it has supplied to head the government at the midterm, and it means a far weaker partner supplying the PM for half the term. Quite unusual.
Regarding list formation:
Herzog is understood to have agreed to place Livni in the second place on the joint party list, as well as giving Hatnua the 6th, 21st and 25th slots on the joint list. The 6th slot was earmarked for former environment minister [and once Labor Party leader] Amir Peretz.
Those same polls still suggest the right would be more likely to form the government. (So far, Likud is probably losing votes to Bennet’s nationalist-Orthodox party, not to the center or left.) Is this a game changer that would attract enough votes off some of the right-wing parties? I would not count on it, but that’s obviously the intent.
