Polish top bank PKO BP was fined PLN 2.84 million for misleading advertisement of its loan "Max pozyczka, mini rata", while peer Pekao was fined PLN 1.83 million for delays in informing credit reports agency BIK about credit repayment, anti-trust body UOKiK said in a statement.

"According to UOKiK terms of granting the loan were illegible for an average consumer," UOKiK said in reference to PKO BP. The ad was aired between October and December 2010.

In case of Pekao, the bank has already abandoned the practice in question, UOKiK said.

Raiffeisen Bank saw UOKiK impose PLN 1.83 million fine on the bank for charging the clients for costs of real estate valuation in case of delays in mortgage loan repayment, UOKiK said in the statement.
