Bulgaria has done its duty by informing its partners in Nato and the European Union about classified information leaks at Bulgaria’s State Agency for National Security (SANS).

The news came from Tvseta Markova, head of the State Commission on Information Security (SCIS), who appeared on Bulgarian National Radio (BNR) on October 30 2009.

SCIS activities are related to the organisation, co-ordination and control of the country's classified information protection.

According to Markov, the SANS reports, which have leaked to the internet, did not threaten in any way Bulgaria’s national interest and the country's obligations to Nato.

She was referring to the recent scandal about former prime minister Sergei Stanishev and whether he had, while prime minister, adhered to rules on handling classified information.

Prime Minister Boiko Borissov said that there were between nine and 10 reports with classified information missing from Cabinet records. Some of the reports contained information for possible adoption by the US finance department aimed at Bulgarian banking system, drug channels and tenders of Double-Use items.

Another report allegedly contained information about Russia using its energy policy as a political tool.

The report, which triggered the classified information row, were carried out by SANS in October 2008. Borissov claims that Stanishev did not return a report to SANS after being sent it, as procedures required.

The report, said to have contained data about former government officials allegedly involved in corruption, appeared on October 24 2009 in the hands of a SANS former employee who handed it to Borissov. A few days later, it was published on the internet, followed by another report.
