Václav Klaus led ODS since its foundation in 1991. Party was in opposition since 2002 but supported minority cabinet of Miloš Zeman. ODS hoped to win 2002 legislative election but was defeated by ČSSD. Klaus then decided to not seek another term as leader of ODS and decided to run for presidency instead. New leader was to be elected at congress in Františkovy Lázně. On 22 September 2002, Evžen Tošenovský announced his candidacy. Jan Zahradil reacted with an announcement that he will run against Tošenovský. Tošenovský withdrew from election on 8 November 2002. He was the only official candidate at the time. In early November 2002, Mirek Topolánek and Miroslava Němcová announced their candidacy. On 20 November 2002, Petr Nečas announced his candidacy. Pavel Bém stated that he will announce candidacy on 28 November 2002. Petr Nečas and Jan Zahradil were considered main candidates for the chairmanship as they were supported by strongest regional organisations. Nečas was endorsed by South Moravian ODS and Zahradil by Prague ODS. Other candidates were Mirek Topolánek and Miroslava Němcová. Zahradil also received nomination from Plzeň and Ústí organisations. Nečas then received nomination from Moravia-Silesia which was Topolánek's home regional organisation.

Mirek Topolánek, who was considered the least preferred candidate for Klaus, praised Klaus' role in party. He stated that ODS should embrace Klausism as its ideology. Miroslava Němcová declined to make a speech. It was expected that Petr Nečas and Jan Źahradil will face each other in the second round but Zahradil was eliminated and Topolánek became Nečas' rival for the second round. Nečas was considered the front-runner but Topolánek received more votes and became the new leader.
Aftermath

Klaus reportedly wasn't pleased by the result and was seen sending a text message in which he called Topolánek "absolutely dry hollow poplar." According to Topolánek Klaus accepted the result correctly. Klaus himself stated that he doesn't have a problem with Topolánek but with people who pushed Topolánek to the position with expectations that are different than expectations of Mirek Topolánek Topolánek led ODS to 2006 legislative election and became the Prime Minister of the Czech Republic.
