A Hungarian authority tasked with defending the country's sovereignty against foreign influence has launched an investigation into the Hungarian branch of anti-corruption organization Transparency International. Transparency International Hungary said on June 25 it had received a six-page letter announcing the investigation from Hungary's newly formed Sovereignty Protection Office, which has been condemned by rights groups as a means to stifle dissent. The authority requested financial and operational information and said it had initiated "a specific and comprehensive investigation" into Transparency International Hungary's activities. The group said it would comply but that it believes the office is unconstitutional.
