History of Israel exchange for the Lebanese terrorist Samir Kuntar, four Hezbollah prisoners, and the bodies of 199 Palestinian Arab and Lebanese fighters. Olmert came under investigation for corruption and this led him to announce on 30 July 2008, that he would be stepping down as Prime Minister following election of a new leader of the Kadima party in September 2008. Tzipi Livni won the election, but was unable to form a coalition and Olmert remained in office until the general election. Israel carried out Operation Cast Lead in the Gaza Strip from 27 December 2008 to 18 January 2009 in response to
Meretz new chairman. On 22 December 2008, Meretz finalized its merger with Hatnua HaHadasha ("The New Movement") for the 2009 Israeli elections. The joint Meretz-Hatnua HaHadasha list ended up winning only 3 seats in the elections. This electoral loss was largely attributed to traditionally left-wing voters choosing to strategically vote for Kadima, in an effort to get Tzipi Livni to head the next government instead of Benjamin Netanyahu of Likud. Following the party's failure in the 2009 legislative elections, some of the party members called for the resignation of the party chairman Haim Oron and to give way for Zehava Gal-On.
