Admitting that efforts to fix Slovenia's ailing banks were behind schedule, she said that the country "has nevertheless taken major steps in the past seven months and we are now waiting only for the results of stress tests that are underway at eight [Slovenian] banks".

She said she was sure that the measures the government would take to fix the banks would "fully restore trust in our banks".

"I would like to emphasise that all the numbers that the media have been speculating about...are only that - utter speculation. We have no indication on the actual numbers...And I would really like to appeal to the media to stop with this speculation, which does nothing but harm Slovenia's interests."

Bratušek discussed efforts to fix Slovenia's banks with European Central Bank (ECB) president Mario Draghi on Thursday evening, but would not provide the details of the meeting today. "These were very constructive talks. But we agreed not to comment on them publicly."

The prime minister said she was satisfied with the outcome of her talks in Brussels and assurance she obtained that the results of the stress tests for Slovenia's biggest banks, NLB and NKBM, from the ongoing reviews would be considered in next year's EU-wide stress tests.

She said it was too early to say to what degree the results would be considered, as the methodology of the EU-wide tests had not yet been decided on, adding that the "steps taken so far and those that will follow will be factored in".

Meanwhile, Bratušek voiced confidence that once the national tests were complete, the bad bank would be able to launch operations in assuming toxic assets.

Furthermore, she voiced confidence that there would be no complications in Slovenia in implementing a legislative change introducing the bail-in rule requiring owners to contribute to capital injections before state aid can be used.

The changes have entered parliamentary passage and could be passed as early as next week, although an association of small shareholders has threatened to challenge them at the Constitutional Court.

She assessed that Slovenia's biggest mistake in the past was to promise a lot but take little action.

"We're a government that is doing the exact opposite. We're not promising a lot, but what we do promise, we carry out. I think we have obtained lot of credibility in European institutions this way."

Bratušek also said that her Positive Slovenia (PS) party had not yet decided on which European political grouping to join despite the fact that she had taken part in a meeting of the European Liberals (ALDE) prior to the EU summit on Thursday.

"I believe that Positive Slovenia is somewhere in between the liberals and socialists, but we need to take this decision jointly. I think it will be made soon," she said.
