Book excerpt: The SDLP has consistently defined the Northern Ireland problem as one of a divided people, rather than a territorial issue. Therefore, it raises the important question: how much revision from the traditional nationalist perspective does the SDLP portray, if at all, from the mid-70s onwards? The major objective of this study is to investigate the tensions within the party over its political identity. From the SDLP viewpoint, the huge 'yes' vote (in the 22nd May, 1998 Referendum after this book went to press), offers the greatest hope in Northern Ireland's history that Catholics and Protestants can live together on the basis of respect and equality.
