Tzipi Livni position on Kadima's list of candidates, which effectively guaranteed her election to the Knesset. In 2006, Livni was appointed as Israel's Minister of Foreign Affairs. She held this position until 2009. In Ehud Olmert's government, Livni was also appointed Designated Acting Prime Minister (also known as Vice Prime Minister), taking the place of the prime minister if he or she is outside the country or temporarily or permanently unable to fulfill his or her duties. She ceased serving as Justice Minister at that time, but again held that position from 29 November 2006 to 7 February 2007, while still serving
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.
