The head of security for Slovak Railways, Ján Gróf, attended a conference in St. Petersburg that was also attended by individuals supporting Russian aggression against Ukraine. This revelation, brought to light by Slovak Progressive party politicians Peter Bátor and Martin Dubéci, has prompted calls for a review by the Slovak Information Service. The conference was reportedly organized by a close associate of Russian President Vladimir Putin. The politicians expressed concern over the potential security implications of Gróf’s attendance, given the connections of other participants. They are now seeking an investigation into the circumstances surrounding his trip and potential risks to Slovak security. The incident raises questions about vetting procedures and potential Russian influence within critical infrastructure sectors. Further scrutiny is expected to follow this disclosure.
