In 1967, young people held mock negotiations in Brussels to work out a treaty of accession for the UK to the Community. In March 1969 they organized a demonstration on the spectators benches of the European Parliament, demanding its direct elections by universal suffrage. In many European countries protest demonstrations were organized against the dictatorship in Greece. These activities helped the first groups of young federalists to set up very close collaboration and to tighten their links again. This collaboration took concrete form in the creation of JEF’s liaison office in 1970. It was there that the international association took the name of ‘Young European Federalists' and the founding Congress was held in Luxembourg on 25 and 26 March 1972.
