Former intelligence official Egisto Ott has been found guilty of spying for Russia, in what has been dubbed Austria's biggest spy trial in years.

A jury in Vienna found Ott, 63, guilty of having handed over information to Russian intelligence officers and to Jan Marsalek, the fugitive executive of collapsed German payments firm Wirecard.

Ott, who denies the charges, was sentenced to four years and one month in prison. His lawyer has appealed against the verdict.

The spy scandal has revived fears that Austria remains a hotbed of Russian espionage activity.

In addition to spying, Ott was found guilty of misuse of office, bribery, aggravated fraud and breach of trust.

The court heard how he had supported "a secret intelligence service of the Russian Federation to the detriment of the Republic of Austria" by collecting secret facts and a large amount of personal data from police databases from 2015 to 2020.

Prosecutors said Ott gave this information to Marsalek and unknown representatives of the Russian intelligence service, and received payment in return.

Marsalek, who is also an Austrian citizen, is wanted by German police for alleged fraud and is currently believed to be in the Russian capital, Moscow, having fled via Austria in 2020.

Alleged to be a Russian intelligence asset, Marsalek is the subject of an Interpol Red Notice and, as such, could be arrested if found in the territory of any of the countries belonging to the 196-member international police organisation.

Prosecutors told the court that Marsalek commissioned Ott to obtain a laptop containing secret electronic security hardware used by EU states for secure electronic communication. The laptop, they said, was handed over to the Russian intelligence service.

Ott was also found guilty of having passed phone data from senior Austrian interior ministry officials to Russia. He obtained the work phones after they accidentally fell into the River Danube on an interior ministry boating trip.

The court heard how he copied their contents and passed them on to Marsalek, and Moscow.

The prosecution told the court that Ott was "not romantic about Russia", but had acted out of financial motives and frustration with work.

Ott denied the accusations in court. He said that he had not worked for Moscow, but had carried out a covert operation in collaboration with a Western intelligence service.

The case has shed light on more of the alleged activities of Marselek, who has since been charged with fraud and embezzlement, suspected of having inflated Wirecard's balance sheet total and sales volume.

Marsalek is also believed to have been the controller of a group of Bulgarians who were convicted in London in 2025 of spying for Russia.

When Ott was arrested in 2024, Austria's then Chancellor, Karl Nehammer, described the case as "a threat to democracy and our country's national security".

Russia and China showed they were shoulder-to-shoulder on the world stage, but it became clear there are limits, says the BBC's Russia Editor.

The unarmed Rivet Joint surveillance aircraft was conducting a "routine international flight" during the incidents, the Ministry of Defence says.

The change reflects increasing supply concerns over certain fuels due to the effective blockade of the Strait of Hormuz.
