The Rey Commission (Belgium) held office from 2 July 1967 to 30 June 1970. It was the first single Commission of the European Community (EC), established by the Merger Treaty (1965). Jean Rey and his commissioners undertook to reinforce the Community institutions and, in particular, to increase the European Parliament’s powers. It campaigned in favour of universal suffrage for the assembly and this then became a reality in 1979. This Commission also saw the completion of the Customs Union (1968).
