On 21 November 2005, Sharon resigned as head of Likud, and dissolved parliament to form a new centrist party called Kadima ("Forward"). November polls indicated that Sharon was likely to be returned to the prime ministership. On 20 December 2005, Sharon's longtime rival Netanyahu was elected his successor as leader of Likud. Following Sharon's incapacitation, Ehud Olmert replaced Sharon as Kadima's leader, for the nearing general elections. Likud, along with the Labor Party, were "Kadima"s chief rivals in the March 2006 elections.
