During the summer there were many expropriations and land occupations promoted by the agrarian reform established by the left, and encouraged by Gonçalves, in the areas of the country where there were larger properties, such as in the
Alentejo. In the north, there were more than 550 violent acts, such as the assault on left-wing party headquarters and bomb attacks by groups such as the Maria da Fonte Movement, which took its name from an
1846 uprising, Spínola's Democratic Movement for the Liberation of Portugal (MDLP), and right-wing supporters of the former
Estado Novo regime. In addition, major disturbances were organized by the CAP (Confederation of Portuguese Farmers). Such activities were occurring at the same time as Portuguese living in its former colonies were returning home. This influx of refugees from
Angola, and other former colonies led to a housing and employment crisis. On 9 July 1975 the
Socialist Party (PS) left the government in protest against the occupation of the offices of the newspaper
República, which was sympathetic to the party, and the government's failure to resolve the situation. The political climate led to the resignation of the fourth provisional government on 8 August. At this time, the "Group of Nine" emerged. This was a moderate faction of the MFA, which drafted the
Document of Nine. Otelo, who had refused to join the fifth provisional government, responded to the
Document of Nine with the
Document of Revolutionary Self-Criticism, also known as the
COPCON Document, in which he advocated grassroots popular power, thereby offering support from the military to the far-left. This led to Portugal being effectively controlled by three blocs, one led by Otelo, another by the PCP, and a third, moderate bloc, by the Group of Nine, which was closely allied to the PS. On 27 August, 24 journalists from the right-leaning
Diário de Notícias (DN) were sacked after they submitted a petition to the management supporting a review of the editorial line, which they denounced as revisionist. The fifth provisional government only lasted for five weeks, with the enforced resignation of Gonçalves after pressure on President
Francisco da Costa Gomes by the moderates. Meanwhile, certain far-left military factions were arming friendly civilian groups, including those responsible for terrorist attacks, such as the
Partido Revolucionário do Proletariado - Brigadas Revolucionárias. On 27 September, protesters attacked Spanish diplomatic missions in
Lisbon,
Porto, and
Évora, to protest against the execution of five far-left
Basque nationalists by the
Franco regime, carried out that same day. Francoist Spain had given refuge to Portugal's 11 March 1975 coup plotters, and since then some members of its government had hinted at the possibility of a military interventionist plan in Portugal, seeking support from the US and
NATO. ==Beginnings of democracy==
