The European Union, on Thursday, sanctioned Russian President Vladimir Putin’s senior aides, including the man known as his chef, over the poisoning of opposition figure Alexei Navalny and Kremlin meddling in Libya’s civil war, reported AFP.

According to the EU, Yevgeny Prigozhin, nicknamed as “Putin’s chef” was sanctioned because his company has done catering for the Kremlin, was undermining peace in Libya by supporting the Wagner Group private military company.

Six other senior aides, which includes the head of Russia’s FSB domestic spy agency, were sanctioned over the attempt to murder Navalny using the Novichok nerve agent.

Prigozhin, a wealthy tycoon close to Putin, is already under US sanctions over his links to the Wagner mercenary outfit, which has been accused of interfering in various conflicts around Africa. The EU, in its official listing, said that Prigozhin had “close links, including financially, to the private military company Wagner Group.”

It said, “In this way, Prigozhin is engaged in and providing support for Wagner Group’s activities in Libya, which threaten the country’s peace, stability and security.”

The listing means he is banned from travelling to the EU and any assets he holds in the bloc will be frozen. EU citizens and companies are also barred from supplying him with funds.

Similar penalties apply to the six listed over Navalny’s poisoning, who include FSB chief Alexander Bortnikov, as well as Sergei Kirienko and Andrei Yarin, both senior members of Putin’s presidential executive office.

EU in its listing said, “It is reasonable to conclude that the poisoning of Alexei Navalny was only possible with the consent of the presidential executive office.” It added that Yarin was part of a special task force charged with countering Navalny’s influence by discrediting him.

The EU also sanctioned Russia’s State Scientific Research Institute for Organic Chemistry and Technology (GosNIIOKhT), which is supposed to be responsible for the destruction of chemical weapons stocks inherited from the Soviet Union.
