Oleg Smolenkov has been pictured for the first time in a photo of him as a Russian foreign ministry employee

The 50-year-old has been widely named in Russia as the CIA asset who was 'exfiltrated' last year by the agency amid fears he was in danger 

He then lived outside Washington D.C. in a $925,000 home under his own name for a year before he was outed  

He's believed to have photographed secret documents on Putin's desk and provided intelligence about Russia's attempts to interfere in the 2016 election

Former FSB general Aleksandr Mikhailov, 68, said that it was 'unlikely' Russia would seek to assassinate the ex-chief of staff for Yuri Ushakov 

When asked if Smolenkov's case would be like the UK's Skripal case, he replied: 'Or a burglar in the parking lot will break his head'
