May 26 (Reuters) - The Czech Republic holds a parliamentary election on Friday and Saturday in which the left-wing Social Democrats will likely win the most votes but may find it difficult to find partners to form a government.
Opinion polls predict a very close result between leftist and centre-right parties -- a common outcome in the central European country -- that may lead to a lengthy coalition building.
Here is a timeline of events since the first elections after the break-up of Czechoslovakia in 1993, which led to the Czech Republic's independence:
June 1996 - Vaclav Klaus reappointed prime minister in first election since independence, leading minority coalition cabinet.
November 1997 - Klaus resigns following the collapse of the coalition. Non-partisan former central bank chief Josef Tosovsky leads a caretaker administration.
Jan. 20, 1998 - Vaclav Havel re-elected by parliament for a second five-year term as president.
June 1998 - Leftist Social Democrats (CSSD) win early elections and form a minority cabinet led by Milos Zeman, backed by the right-wing Civic Democrats.
March 1999 - The Czech Republic joins NATO.
September 1999 - The country jumps out of a recession in Q2 after five quarters of contraction. Growth accelerates to a peak of 7.0 percent in 2007.
June 15-16, 2002 - The CSSD led by Vladimir Spidla comes top in elections, but wins only 70 seats in the 200-seat parliament. Spidla forms coalition with centrist alliance of Christian Democrats and the Freedom Union, which has 101 seats.
Feb. 28, 2003 - Vaclav Klaus is elected president.
May 1, 2004 - Czechs join the European Union following a referendum in June 2003.
Aug. 4, 2004 - Klaus appoints centre-left coalition government of Prime Minister Stanislav Gross, 39 days Spidla quit. The make-up of the ruling coalition remains the same.
April 25, 2005 - Gross resigns over a scandal involving his personal finances. Gross's Social Democrat colleague Jiri Paroubek is appointed prime minister.
June 4, 2006 - The Civic Democrats win the biggest share of votes in election, but not a majority in the lower house of parliament. Centre-right and left-wing parties win 100 seats each in the 200-seat house.
Nov. 8, 2006 - Klaus appoints rightist leader Mirek Topolanek as prime minister for the second time since the inconclusive June election left parliament deadlocked. Topolanek was first appointed to the post in August. Jan. 19, 2007 - Topolanek's new centre-right government narrowly wins a confidence vote, ending political deadlock.
Feb. 15, 2008 - Klaus elected for second five-year presidential term.
July 9, 2008 - The United States signs a pact to build part of a U.S. missile defence shield in the Czech Republic, prompting Russia to say it would react with military means if the shield was deployed. U.S. President Barack Obama dropped plans to deploy the shield on Czech territory in September 2009. The Czech lower house never ratified the agreement.
Jan. 1, 2009 - Czech Republic takes over the rotating EU presidency for six months.
March 24, 2009 - Topolanek's government falls after defectors joined forces with the leftist opposition Social Democrats in a no-confidence motion.
May 2009 - Civic Democrats and Social Democrats agree to back caretaker cabinet, led by non-partisan Jan Fischer.
March 11, 2010 - The Czech economy contracted by 4.1 percent in 2009 as the global crisis hit demand for Czech exports, and the Finance Ministry predicted 1.5 percent growth this year.
May 28-29, 2010 - Parliamentary elections.
