Slovenia, which scraped together funds to bail out its banks in late 2013, is now selling companies including Telekom, Ljubljana airport, flag carrier Adria Airways and No. 2 bank NKBM. Paint and varnish producer Helios has already been sold, as has Fotona, a developer of medical and military laser gear.

"We're making good progress with the sales negotiations," Bratusek told business daily Handelsblatt. "There will be no delays. We will have concluded the sales by the end of the year."

She said the government was currently assessing whether it would sell further public companies or stakes in businesses to private investors, adding that a list of new firms would be ready in two to three months.
