Poland's top economic policymakers met Tuesday to discuss the impact of the global financial crisis, while the main opposition party urged immediate action by the government.

The conservative Law and Justice party called for an agreement by political parties and the government to work with the national bank, financial regulators and labour unions to ward off damage to Poland.

The call for action to stabilize eastern Europe's largest economy came as European Union leaders scramble to respond to the growing Wall Street fallout, which helped send Warsaw's main stock index to its second-lowest close of 2008 on Monday.

Troubling signs are "more and more alarming" and "nobody doubts" the Polish economy will suffer, Law and Justice deputy head Aleksandra Natalli-Swiat said.

"We must act as quickly as possible," she told the Polish Press Agency (PAP).

Prime Minister Donald Tusk's Civic Platform party called the appeal exaggerated and warned against sowing panic in financial markets.

Poland, like most countries in ex-communist eastern Europe, is forecast to post higher growth than the old EU economies even in the current downturn.

While its economy grew at an annual pace of 6.1 per cent in the three months ending June, analysts have slashed their 2009 forecasts to 4 per cent or less.

Parliament is slated to debate the opposition proposal on Thursday.

Civic Platform head Zbigniew Chlebowski warned the opposition against "unnecessary exaggerations" and urged "a responsible approach."

"It's not like nothing is being done," he told PAP. "But you can't bring panic into the market. Or else it could end badly."
