Parti ouvrier français
A general amnesty in 1880 enabled Malon to return to France, where he resumed work as a journalist and became involved in the new French Workers' Party (POF) of Jules Guesde. In 1882, the party split between 'orthodox' Marxists around Guesde and reformist 'possibilists' led by Paul Brousse. Malon sided with Brousse and helped organise the Federation of the Socialist Workers of France (FTSF).
