PRAGUE (AP) -- The demonstrators from all over the country are urging the government to abandon the cuts and resign.
They also are demanding early parliamentary elections.
The center-right government says the budget cuts and reforms of pension and health care plans are needed to bring the budget deficit back below 3 percent of GDP and maintain market reliability.
Saturday's protest is organized by major labor unions and non-governmental groups.
Recently, several members of a junior coalition partner in the government have quit their party because of a bribery scandal.
Elections are planned for 2014.
