Alliance of Free Democrats
The Pan-European Picnic was organised by four Hungarian opposition parties: the Hungarian Democratic Forum, the Alliance of Free Democrats, Fidesz, and the Independent Smallholders, Agrarian Workers and Civic Party. Its patrons were Christian Social Union in Bavaria, MEP Otto von Habsburg (head of the house of Habsburg and claimant of the Austro-Hungarian throne) and Hungarian Minister of State and reformer Imre Pozsgay.
