Former leaders Ehud Olmert and Tzipi Livni announced on Wednesday they were discussing a partnership that could shake up Israeli politics and lead to a joint campaign to defeat Prime Minister Binyamin Netanyahu in a January election.
A statement from an aide to Olmert said he and Livni had agreed "action must be taken to change the leadership", citing what it called "Israel's deteriorated status" under Netanyahu. It alluded to tensions with the United States about how to rein in Iran's nuclear program and diplomatic paralysis with the Palestinians.
Both agreed to continue meeting and a confidant who spoke on condition of anonymity confirmed Israeli media reports that they were weighing the prospect of a joint election run. A Livni aide also confirmed these talks took place.
It was not clear whether the pair would join one of Israel's center or left-leaning parties, or form their own.
