During their time in Brussels, Durruti and Ascaso were involved in numerous conspiracies. In January 1929, they collaborated in a plot by José Sánchez-Guerra to overthrow Primo de Rivera. The plot was unsuccessful, but it resulted in mobilisation of the CNT and the wider Spanish anarchist movement. In December 1929, Durruti and Ascaso were implicated in an alleged plot by Camillo Berneri to assassinate Belgian princess Marie-José and Italian prince Umberto, but the plot was eventually discovered to have been fabricated by the authorities of Fascist Italy. Berneri was deported, but Durruti and Ascaso were allowed to remain in the country. The following month, on 28 January 1930, Miguel Primo de Rivera was removed from power and his dictatorship in Spain collapsed. As the Spanish anarcho-syndicalist movement was revived, many anarchist exiles began to return to the country. Durruti and Ascaso were themselves tempted to return, but as many of the repressive structures of the dictatorship remained in place, cautioned them to wait for the right moment.
