Unrestrained lending by state owned banks, corruption and cronyism, have led to an increase in non-performing loans and bad debt. Slovenia's government banks made extensive loans for leverged management buyouts of state owned companies in the period 2000-2010. Loans for construction projects also soured, with the capital Ljubljana having many unfinished construction sites. Bad debt at the banks is estimated at 6.8 billion euros, or 19% of Slovenia's GDP, larger than the 16% of GDP for bad debt in Spain. The anti-corruption agency reports large amounts of undisclosed income for the head of the outgoing government, and the outgoing leader of the opposition party who was Mayor of Ljubljana. An election law that requires an endorsement from members of parliament for people seeking to contest elections for the first time makes it difficult to bring new faces and thinking into parliament.
