MOSCOW/PARIS, Jan 8 (Reuters) - Laurent Vinatier, a French researcher serving a three-year prison sentence in Russia for violating Moscow's foreign agent laws, has been freed as part of a prisoner exchange, French and Russian officials said on Thursday.
President Emmanuel Macron posted on X: "Our compatriot Laurent Vinatier is free and back in France. I share the relief felt by his family and loved ones." He added he was grateful for work done by French diplomatic officials.
Russia's FSB security service said Vinatier, 49, had been swapped for Daniil Kasatkin, a Russian basketball player who was arrested at a Paris airport last June and who was wanted in the United States for alleged involvement in ransomware attacks.
The FSB said Vinatier had been pardoned by President Vladimir Putin, who promised last month to look into the case after a French journalist raised it during the Kremlin leader's annual news conference.
Vinatier was arrested by the FSB at a Moscow restaurant in June 2024, and convicted in October that year of breaking laws requiring individuals deemed to be "foreign agents" to register with the Russian authorities.
While behind bars, he was placed under additional investigation for espionage, and he had been facing a likely further trial in coming months.
The FSB statement alleged that Vinatier, acting on instructions from Swiss intelligence, had collected sensitive political and military information - including on combat and training plans - that could have been used to harm Russia's security. However, it said the case had been dismissed because of his "active repentance".
At the time of his arrest, Vinatier was working for the Centre for Humanitarian Dialogue (HD), a Swiss-based conflict mediation organisation. Fellow academics said he was a respected scholar involved in legitimate research.
At his trial, Vinatier said he loved Russia, apologised for breaking the law, and even recited a verse by Russian poet Alexander Pushkin.
TENSE RUSSIA-FRANCE RELATIONS
His release comes amid a period of tense relations between Paris and Moscow over the war in Ukraine. Macron has been an outspoken ally of Kyiv - and has often drawn Russia's ire - but he has also expressed a willingness to engage with Moscow directly to bring about an end to the war.
France had maintained Vinatier was arbitrarily detained and had called for his release. Macron denied that Vinatier worked for the French state and described his arrest as part of a misinformation campaign by Moscow.
Kasatkin, the Russian released in France, had denied the U.S. hacking accusations. His lawyer, Frederic Belot, said he had no computer knowledge but was using a second-hand device that was controlled by cybercriminals.
Belot, who represents both Vinatier and Kasatkin, said Kasatkin had left France by plane and arrived back in Moscow on Thursday.
