In the months after liberation, the political situation in Greece was extremely unstable: following month-long clashes between government and British forces and the guerrillas of EAM-ELAS, the Treaty of Varkiza had resulted in the latter's disarmament. However the situation remained explosive. The moderate government of Nikolaos Plastiras resigned under British pressure on 8 April 1945, and the Regent, Archbishop Damaskinos of Athens, appointed Voulgaris to head an interim government.
