In August 1955, Adnan Menderes the Turkish president at the time, announced that Turkey wouldn't accept any change in the status quo of Cyprus which were not in Turkeys interests. In Turkey, the public opinion was un-eased. Rumors were spreading in Turkish media that a slaughter of the Turkish Cypriot community was likely to occur. Though they were unfounded they led to nationalist reactions in the country and the government-sponsored anti-Greek Istanbul pogrom of September 1955. At the same time, during the London Trilateral Conference between Britain, Turkey and Greece, an agreement failed to materialize due to Turkish intransigence. During a meeting between the end of August and 7 September 1955, Turkey also argued that if the status quo of Cyprus under a British administration would not be respected, the whole Treaty of Lausanne would be questionable.
