Warsaw - The Polish National Bank has prepared a "package of trust" to preserve the stability of Poland's banking system, president of the bank Slawomir Skrzypek said on Monday.

"We want to propose certain structures," Skrzypek said, "thanks to which the Polish National Bank will influence a growth in trust for transactions between banks."

Skrzypek said more details will be given during a meeting with banks on Tuesday.

The conservative Law and Justice party recently 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.

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

An upcoming European Union summit on the financial crisis has also caused a spat between Tusk and President Lech Kaczynski - who co-founded Law and Justice - on who should lead the Polish delegation in the talks. (dpa)
