About 200 opponents of the conservative Law and Justice party led by the prime minister have gathered near the Sejm, where the liberal Civil Platform party, the largest in parliament, the Democratic Left Alliance and the Polish Peasant Party have called for an extraordinary session.
A political crisis broke out in Poland following a television broadcast Tuesday showing backroom political deal-making between a government official and an MP.
The national TVN channel broadcast a videotape recorded using a hidden camera, which showed Adam Lipinski, state secretary of the office of the prime minister and his political aide, offering Renata Beger, a member of parliament from the Self-Defense party, the post of deputy agriculture minister on condition she join the Law and Justice party led by Prime Minister Jaroslaw Kaczynski.
Beger reportedly agreed to be part of the journalistic sting.
The opposition has demanded the immediate resignation of Prime Minister Jaroslaw Kaczynski, whose twin brother, Lech, is the president.
But the government cane out fighting Wednesday, saying it had no plans to quit.
"The government's resignation is not under consideration," said spokesman Jan Dziedziczak.
Law and Justice have reportedly begun talks with members of other parliamentary factions in order to secure a majority for a planned no-confidence vote against the government.
Poland's government coalition, which was formed in spring, broke up in September over budget differences and plans to send more troops to Afghanistan between the conservative Law and Justice party and the rural Self-Defense party.
Civil Platform leader Donald Tusk, who demanded Tuesday the resignation of the government, said Poland was in crisis.
"This is political corruption, and attempts by senior government officials to buy deputies are immoral," Tusk said.
Tusk also said he was urging early elections to deter the sort of anti-government protests that hit another former Communist-bloc country, Hungary, last week.
