Auxiliary associations are a typical feature of Christian Democratic Party organisation, which practice was carried over into the European People's Party (EPP) whose rules of procedure provided for their formation. The demarcation here between the 1970s and the two preceding decades of integration development is underlined by the virtual absence during the latter of any significant developments in the area of transnational party organisation. The construction of Europe should lead through the development of a uniform economic zone to a political community. Each subworking group had one representative from every national member party, and was assisted by a secretary, either from the Euro-parliamentary group or an equivalent expert employed by the European Commission and of Socialist affiliation.
