The foundation of philanthropist George Soros has said it is closing its office in Hungary, blaming the move on an “increasingly repressive” environment.
Open Society Foundations (OSF), which funds non-governmental organisations (NGOs), says it will move its operation to the German capital, Berlin.
Hungarian Prime Minister Viktor Orban’s right-wing government has said it plans to tighten restrictions on NGOs.
Re-elected last month, Mr Orban campaigned under a “Stop Soros” banner.
Mr Soros denies Mr Orban’s accusation that his foundation is part of a plan to bring migrants to Europe in order to undermine nation states.
OSF has been under sustained verbal and legal attack by the Fidesz government for the past three years, the BBC’s Nick Thorpe in Budapest reports.
