Former intelligence official Egisto Ott goes on trial in Vienna on Thursday, accused of spying for Russia in what is being dubbed Austria's biggest spy trial in years.
Egisto Ott, 63, is charged with having handed over information to Russian intelligence officers and to Jan Marsalek, the fugitive executive of collapsed German payments firm Wirecard.
Ott denies the charges.
Jan Marsalek, who is also an Austrian citizen, is wanted by German police for alleged fraud and is currently believed to be in Moscow, having fled via Austria in 2020.
The subject of an Interpol Red Notice, he is alleged to be an intelligence asset for the FSB, Russia's secretive security service.
