Ukrainian interpreter who visited May arrested on Russian spying charges

An employee of the Cabinet of Ministers, Stanislav Yezhov, who was detained on December 20, has been notified of suspicion in committing a crime, the press center of the Security Service of Ukraine (SBU) has reported.

A Ukrainian government official has been detained on charges of spying for Russia, Ukraine's security agency said Thursday.

Ukrainian media reports identified the suspect as an aide to Prime Minister Volodymyr Groysman who accompanied him on foreign trips.

Stanislav Yezhov was reportedly pictured with Theresa May in Downing Street in July.

'The action that's been taken is a matter for the Ukrainian authorities'.

They allege he passed on data to the Russians through "electronic channels of communication". The Kremlin is aware of Stanislav Yezhov's detention in Ukraine on charges of treason in favor of Russian Federation.

Yezhov, 39, has long worked for Ukrainian government.

Yezhov's wife is a Russian citizen and he could have been blackmailed or pushed to work for Russia, he added, urging him to cooperate with the investigation.

Mr Yezhov was seen in photographs interpreting for Ukraine PM Volodymyr Groysman at a meeting with Mrs May at Downing Street in July, as well as a meeting with Joe Biden, then United States vice president, in 2016.

Photos on what appears to be his social networking profile on Russian website VK show him on trips with Groysman, including sat behind the prime minister during talks with former U.S. vice president Joe Biden.

Its release said: "The SBU operatives documented that the offender by the order of Russian curators collected data on the activities of governmental institutions by means of special equipment". SBU opened a criminal case for state treason.
