Spain's governing Popular Party insists its financial accounts are totally legal and denies a newspaper report of regular under-the-table payments to leading members, including current Prime Minister Mariano Rajoy.
In a statement Thursday the party denied the existence of "hidden accounts" or "the systematic payment to certain people of money other than their monthly wages."
Leading newspaper El Pais published what it called the "secret accounts" of former treasurer Luis Barcenas, with copies of alleged account sheets from several years ago showing names and amounts received. The money was allegedly paid by outside firms via Barcenas.
The scandal first broke when after the National Court reported that Barcenas amassed an unexplained €22 million ($30 million) in a Swiss bank account several years ago.
