Stoyan Stoyanov, deputy director of the Social Activities Agency (SAA) of the Defense Ministry, was expected to hand in his resignation following an announcement by the  State Agency for National Security (SANS) that Stoyanov's access to classified information had been revoked.

SANS said it had decided to revoke Stoyanov's access following a decision by the military prosecution to start pre-trial proceedings against Stoyanov. Without access to classified information, Stoyanov would be unable to fulfill his job and was expected to be released, Bulgarian daily Dnevnik quoted unnamed sources at the Defense Ministry as saying.

According to Bulgarian broadcaster mediapool.bg, the letter from SANS revoking Stoyanov's access to classified information was received at the Defence Ministry on January 23, the same day Stoyanov went on sick leave.

When Stoyanov would return from his sick-leave he was expected to leave his post, mediapool.bg said.

As deputy director of the SAA, Stoyanov, popularly known by his nickname Stoutsi and as the owner of a Lamborghini Countach which local media estimate at worth two million euro, was in charge of army residence in Lozenetz, the Central Military Club in Sofia and the military TV channel, among others.

Before his current position, Stoyanov was head of the Agency for Military Clubs and Information at the Defence Ministry, which oversaw the construction of a massive office space complex on Skobelev Boulevard in Sofia.

The project, which has meanwhile been axed and announced to be for sale, had cost the Defence Ministry by December 2008 a total of 19 million leva, mediapool.bg said.

According to information from Sofia Military Prosecutor's Office, quoted by mediapool.bg, the investigation under way was started after an audit report from the Audit Directorate of the Defense Ministry into possible irregularities in connection with the construction of the Skobelev Boulevard building, as well as misuse of buildings and military clubs in the country.
