The next Czech legislative election will take place on May 28-29, 2010. They were expected to take place some time before the end 2009 (originally set for 9–10 October 2009) to elect the members of the Chamber of Deputies of the Czech Republic. Incumbent PM Mirek Topolánek had lost a no-confidence vote on March 24, 2009. After four failed earlier attempts, the opposition ČSSD party succeeded in leading the lower house of the Czech parliament to a no confidence vote in Topolánek's government. The measure passed with 101 votes to 96, largely due to several members of Topolánek's own party voting with the opposition.
