Czech officials say embattled Prime Minister Stanislav Gross will face a parliamentary vote of no-confidence Friday.
The announcement came as the Christian Democratic Party, a junior partner in Mr. Gross' ruling coalition, said it will meet Wednesday to consider pulling out of the government.
The Christian Democrats have asked Mr. Gross to step down. The prime minister is facing questions about his finances and his purchase of an apartment in Prague six years ago - as well as his wife's business activities.
However, the Social Democrats on Saturday backed a motion for keeping Mr. Gross as prime minister and party leader until scheduled elections next year.
Separately, the head of the opposition Communist Party said he will urge his party legislators to support the no-confidence motion proposed by another opposition party, the Civic Democrats.
