KDU-ČSL, often shortened to lidovci, is a Christian-democratic political party in the Czech Republic. The party has taken part in almost every Czech government since 1990. In the June 2006 legislative election, the party won 7.2% of the vote and 13 out of 200 seats; but in the 2010 election, its vote share dropped to 4.4% and they lost all of its seats. The party regained its parliamentary standing in the 2013 legislative election, winning 14 seats in the new parliament, thereby becoming the first party ever to return to the Chamber of Deputies after previously dropping out.

Miroslav Kalousek is a Czech politician, former leader of KDU-ČSL and TOP 09, and a member of the Chamber of Deputies (MP) from 1998 until his resignation in 2021. He served twice as Finance Minister in the cabinets of Mirek Topolánek and then again from 2010 to 2013 in the government of Petr Nečas.
