We have learnt with deep regret that Gyula Horn, former Prime Minister of Hungary passed away. The European left lost one of his most charismatic personalities. Gyula Horn had a key role in the reunification of Germany and the peaceful political transition of Hungary in 1989. The first socialist Prime Minister after the transition, his committed work towards Hungary's membership to the EU was crucial during the accession negotiations. Our thoughts go out to his family in this difficult time.
