the first round of peace talks took place in geneva, switzerland between 25 and 30 july 1974, james callaghan, the british foreign secretary, having summoned a conference of the three guarantor powers. there they issued a declaration that the turkish occupation zone should not be extended, that the turkish enclaves should immediately be evacuated by the greeks, and that a further conference should be held at geneva with the two cypriot communities present to restore peace and re-establish constitutional government. in advance of this they made two observations, one upholding the 1960 constitution, the other appearing to abandon it. they called for the turkish vice-president to resume his functions, but they also noted 'the existence in practice of two autonomous administrations, that of the greek cypriot community and that of the turkish cypriot community'.
