In Greece's state-financed political system, parties that receive more votes get more funding. Relying on past good results, the big political parties have pledged future state funding as collateral for bank loans. But in the most recent poll their support collapsed, leaving them with big loans and facing much smaller incomes. 

Banking sources familiar with the issue say that conservative New Democracy and socialist Pasok now owe a combined 232 million euros to Greek banks. Some of the loans are going unpaid, those sources say. The debts far exceed the combined 37 million euros the parties received in state funding last year - a figure set to decline.
