Transnational Party Co-operation and European Integration [PDF ebook] 
The Process Towards Direct Elections

In this book, first published in 1981, the authors trace and analyse the growth of transnational party co-operation and the factors important to it during the years before and immediately following direct elections. They recognise three major dimensions of transnational co-operation: the Euro-parliamentary groups; the new European party federations; and the national party frameworks in the member states. This title will be of interest to academics and students concerned with European affairs.
