Nov 7 (Reuters) - Czech President Vaclav Klaus said on Tuesday he will name rightist leader Mirek Topolanek as Czech prime minister on Wednesday. Topolanek will seek to form a government, but faces a tough task because his Civic Democrats, along with two centrist allies, control the same number of seats as leftists in the 200-seat lower house. Topolanek was appointed prime minister once before after the June general election. His first minority government lost a parliamentary no-confidence vote. Here are five facts about the rightist leader: * The Civic Democrat chief, 50, is a trained engineer and businessman. * Elected leader of the Civic Democrat party in 2002, he replaced Vaclav Klaus, the president and the country's most popular politician. * A father-of-three, he won the most votes, but not a majority, in a June 2-3 election and must cobble together a cabinet either with the tacit support of the left or with the help at least one deputy who crosses the floor or abstains from voting. * He stands on the pragmatic side of his conservative party. He supports European Union enlargement, but opposes further integration and says euro entry is necessary once reforms are made to secure long-term financial stability. * Married, Topolanek is an avid sportsman. He is often seen on Prague's tennis courts, and cycles regularly.
