Italian anti-fascists started to emigrate from the moment that Mussolini seized power. These émigrés, or fuorusciti, tried to organise themselves to put an end to Mussolini’s regime, but found themselves confronting a number of unexpected difficulties in their host countries. Among them, Giustiza e Libertà (GL) was one of the most active organisations. One of the problems they had to face was the issue of how best to deal with their hosts without compromising their integrity as Italians, and as patriots. The case of Paolo Vittorelli (Raffaele Battino), who is the subject of this article, presents a clear case study of this issue and shows how close collaboration between Italian anti-fascists and western democracies (in this case, the United Kingdom) was hindered by ideological problems. The study of such episodes helps us to shed light not only on the mentality of the GL émigrés, but also on the way the Italian Resistance would later approach the issue of working together with the Allies during the Italian campaign of 1943–1945.
