Stewart Lloyd-Jones, ISCTE (Lisbon), Portugal's history since 1974, "The Portuguese Communist Party (PCP–Partido Comunista Português), which had courted and infiltrated the MFA from the very first days of the revolution, decided that the time was now right for it to seize the initiative. Much of the radical fervour that was unleashed following Spínola's coup attempt was encouraged by the PCP as part of their own agenda to infiltrate the MFA and steer the revolution in their direction.", Centro de Documentação 25 de Abril, University of Coimbra
