WARSAW -- The new scandal mesmerizing Poland seems lifted from a Cold War dossier: Spies, oil traders, a polo player, and a billionaire are tangled in a rumored plot by Moscow to manipulate its smaller neighbor.
''It's a sad, ridiculous story about corruption and political vendettas," said Ryszard Maria Owczarek, a painter who has been avidly following the tale of death threats and rumored bribes that have absorbed the Polish media. ''Many ugly things will come out. The dirt is already being heaped."
The focus of intrigue is Jan Kulczyk, this country's richest man and a friend to President Aleksander Kwasniewski. A special committee of Parliament is investigating allegations that Kulczyk, acting with the president's blessing, met with a former Russian spy to negotiate the sale of an important oil refinery to a Moscow-controlled corporation.
The possibility of Russia consolidating more control over Poland's oil industry is an unsettling prospect for a nation that last century lived under the fist of a Russian czar and Soviet apparatchiks.
Russian companies supply much of the oil to former Soviet bloc nations, and Polish intelligence says this domination allows Moscow to meddle in the political affairs of Lithuania and the Czech Republic, among other countries.
Russia's president, Vladimir V. Putin, ''wants to use the power of big Russian companies to rebuild imperial politics in different ways -- not with tanks, but with oil pipes to make the countries in the sphere of Moscow's influence dependent upon raw materials," said Piotr Stasinski, deputy editor of Poland's leading newspaper, Gazeta Wyborcza.
Kulczyk has denied wrongdoing but has yet to appear before the special committee. Kwasniewski has accused the committee's right-wing politicians of orchestrating a ''witch hunt" and a ''creeping coup" to disgrace him and his leftist party.
According to evidence heard by the committee, Polish intelligence said Kulczyk met in a restaurant in Vienna in summer 2003 with Vladimir Alganov, a former KGB agent whose contacts with politicians in the 1990s helped bring down the Polish government. Alganov is an executive in a Russian- owned oil venture that was seeking to buy Poland's refinery in the port of Gdansk.
Poland imports about 90 percent of its oil and gas from Russia. The Gdansk refinery would offer Warsaw some protection against shortages or price-gouging by Moscow.
Kulczyk's meeting with Alganov came to light during an investigation into PKN Orlen, Poland's largest oil company. Kulczyk is a shareholder in Orlen.
The investigation led to the arrest of Marek Dochnal, a Polish lobbyist and polo player accused of offering a Polish politician a Mercedes in exchange for the government steering oil and steel contracts to Russian firms.
Deciphering what, if anything, may have occurred between Kulczyk and Alganov has proved more vexing. Kulczyk is one of Poland's most powerful men. His business interests include communications, highway construction, cars, energy, and insurance.
As the scandal widened in recent weeks, Kulczyk checked into a clinic in London with heart problems and canceled an appearance before the special committee. He recently returned to Poland and was slated to testify Tuesday.
Polish intelligence has disclosed only some of what it knows about the case.
The intelligence community is split in its support for Kwasniewski and his right-wing opponents; different players have leaked competing stories to bolster their side.
The parliamentary committee investigating the case has been accused of divulging only information damaging to Kulczyk and the president. At least one right-wing committee member said Kulczyk committed treason and the president should be impeached.
''It will be difficult for the president to survive this," said Zbigniew Wasserman, a conservative on the committee. He said Kwasniewski and other leftist politicians and businessmen were using Orlen to benefit their political parties while tapping Polish intelligence agencies ''to act as a protective umbrella for those in power."
''This scandal shows that talk of free markets and capitalism are just slogans," said Wasserman, adding that he had received threats. ''This reveals it's all about who you know."
